    SELYA, Circuit Judge.        This case comes before us for a
    second time, albeit in a different posture.             The issues are much
    the same, though presented in sharper focus on a better-developed
    record.   As such, they conjure up what might be described, in a
    turn of phrase popularly attributed to Lawrence "Yogi" Berra, as
    a sense of "déjà vu all over again."1
    The case has its genesis in a suit filed by plaintiffs
    Harold Shurtleff and Camp Constitution in which they complained
    that the defendants — the City of Boston and Gregory T. Rooney, in
    his   official   capacity    as    Commissioner    of    Boston's   Property
    Management Department (collectively, the City) — trampled their
    constitutional   rights     by    refusing   to   fly   a   pennant,   openly
    acknowledged by the plaintiffs to be a "Christian Flag," from a
    flagpole at Boston City Hall.        The district court granted summary
    judgment in favor of the City.          See Shurtleff v. City of Bos.
    (Shurtleff III), No. 18-CV-11417, 
    2020 WL 555248
    , at *6 (D. Mass.
    Feb. 4, 2020).    Concluding, as we do, that the government speech
    doctrine bars the maintenance of the plaintiffs' free speech claims
    and that their remaining claims under the Establishment Clause and
    the Equal Protection Clause lack bite, we affirm.
    1We say "popularly attributed to" because at least one
    scholar has declared that "although this [phrase] is commonly cited
    as a 'Berra-ism,' Yogi Berra denies ever saying it." Ralph Keyes,
    "Nice Guys Finish Seventh": False Phrases, Spurious Sayings, and
    Familiar Misquotations 152 (1992).

    I. BACKGROUND
    We begin by rehearsing the relevant facts (most of which
    are undisputed, though the inferences from them are not) and the
    travel of the case.      The City owns and manages three flagpoles in
    an area in front of City Hall referred to as City Hall Plaza.            The
    three flagpoles are each approximately eighty-three feet tall and
    are prominently located in front of the entrance to City Hall —
    the seat of Boston's municipal government.          Ordinarily, the City
    raises the United States flag and the POW/MIA flag on one flagpole,
    the Commonwealth of Massachusetts flag on the second flagpole, and
    its own flag on the third flagpole.              Upon request and after
    approval, though, the City will from time to time replace its flag
    with another flag for a limited period of time.
    Such requests are typically made by a third party in
    connection with an event taking place within the immediate area of
    the flagpoles.   In welcoming these third-party banners, the City's
    website proclaims that the City seeks to "commemorate flags from
    many countries and communities at Boston City Hall Plaza during
    the year" (emphasis in original). The opportunity to display these
    kinds of flags was created in order to establish "an environment
    in the City where everyone feels included, . . . to raise awareness
    in Greater Boston and beyond about the many countries and cultures
    around   the   world[,   and]   to    foster   diversity   and   build   and
    strengthen connections among Boston's many communities."
    - 4 -
    In addition to these flag-raisings, the City also allows
    organizations to hold events in several locations near City Hall.
    Endeavoring to educate those who may be interested in hosting such
    an event, the City has published event guidelines on its website.
    The guidelines make clear that people need the City's permission
    to hold events at City-owned properties and direct interested
    parties to an application form.
    The application form (which is available either online
    or as a document) allows applicants to designate the location at
    which they wish to hold an event, listing six options:                  Faneuil
    Hall, Sam Adams Park, City Hall Plaza, the City Hall Lobby, the
    City   Hall    Flag    Poles,   and    the   North   Stage.    Although   those
    interested      in    hosting   a     flag-raising    event   must   submit   an
    application form, neither the electronic nor the written version
    of the form mentions the option of raising a flag on any of the
    City's three flagpoles.
    Once the City receives an application, its policy and
    practice are to perform an initial review.               The purpose of this
    review is in part to ensure that there are no conflicting events
    occupying the same space, that the application is complete and
    accurately describes the proposed event, that the event would not
    endanger the public, and that other administrative requirements
    have been satisfied.
    - 5 -
    The obligation to review and act upon applications falls
    into Rooney's domain.    Before a flag-raising event is approved,
    Rooney must determine that the City's decision to raise a flag is
    consistent with the City's message, policies, and practices.   Each
    applicant submits a short description of the flag that it wishes
    to hoist (e.g., "Portuguese Flag"), and it is Rooney's invariable
    practice to act upon the flag-raising request without seeing the
    actual flag.    The record makes manifest that Rooney has never
    sought to look at a flag before approving an application.        If
    Rooney concludes that the event meets the City's standards, he
    then approves the flag-raising event.   And if a flag-raising event
    is disapproved, the City offers the applicant the opportunity to
    hold the proposed event, without the flag-raising, either at City
    Hall Plaza or at some other location.
    In a twelve-year period (from June 2005 through June
    2017), the City approved 284 flag-raising events that implicated
    its third flagpole.   These events were in connection with ethnic
    and other cultural celebrations, the arrival of dignitaries from
    other countries, the commemoration of historic events in other
    countries, and the celebration of certain causes (such as "gay
    pride").   The City also has raised on its third flagpole the flags
    of other countries, including Albania, Brazil, Ethiopia, Italy,
    Panama, Peru, Portugal, Mexico, as well as China, Cuba, and Turkey.
    So, too, it has raised the flags of Puerto Rico and private
    - 6 -
    organizations,      such   as      the     Chinese   Progressive     Association,
    National     Juneteenth         Observance        Foundation,       Bunker       Hill
    Association, and Boston Pride.              Broadly speaking, we group these
    approvals    as    approvals       for     "the   flags    of   countries,      civic
    organizations, or secular causes."
    Against this backdrop, we introduce the plaintiffs.
    Camp Constitution is an all-volunteer association that seeks "to
    enhance    understanding      of     the    country's     Judeo-Christian       moral
    heritage."        Shurtleff     is    the    founder      and   director   of   Camp
    Constitution. In July of 2017, the plaintiffs emailed Lisa Menino,
    the City's senior special events official, seeking leave to fly
    their own flag over City Hall Plaza.              In their words, the proposed
    event would "raise the Christian Flag" and feature "short speeches
    by some local clergy focusing on Boston's history."
    At the time of this request, the City had no written
    policy for handling flag-raising applications.                     What is more,
    Rooney had never before denied a flag-raising application.                         On
    this occasion, though, the plaintiffs' request "concerned" Rooney
    because he considered it to be the first request he had received
    related to a religious flag.
    Of course, some of the flags that the City had raised
    contained religious imagery.             The Portuguese flag, for instance,
    contains "dots inside blue shields represent[ing] the five wounds
    of Christ when crucified" and "thirty dots that represent[] [sic]
    - 7 -
    the coins Judas received for having betrayed Christ."          As another
    example, the Turkish flag situates the star and crescent of the
    Islamic Ottoman Empire in white against a red background.           Indeed,
    the City's own flag includes a Latin inscription, which translates
    as "God be with us as he was with our fathers."        None of the flags
    that the City had previously approved,          however, came with a
    religious description.
    Mulling the plaintiffs' application, Rooney conducted a
    review of past flag-raising requests and determined that the City
    had no past practice of flying a religious flag.          He proceeded to
    deny the plaintiffs' flag-raising request.          In response to the
    plaintiffs'   inquiry   into   the   reason   for   the   denial,    Rooney
    responded that the City's policy was to refrain respectfully from
    flying non-secular third-party flags in accordance with the First
    Amendment's prohibition of government establishment of religion.
    Rooney offered to fly     some non-religious flag         instead.     The
    plaintiffs spurned this offer.
    In September of 2017, Shurtleff once again requested
    permission for a flag-raising event at City Hall Plaza. This time,
    he submitted a flag-raising application that titled the event as
    "Camp Constitution Christian Flag Raising."         The event, which was
    intended to "[c]elebrate and recognize the contributions Boston's
    Christian community has made to our city's cultural diversity,
    intellectual capital and economic growth," would feature three
    - 8 -
    speakers:     Reverend Steve Craft (who would speak on the need for
    racial reconciliation), Pastor William Levi (who would speak on
    "the blessings of religious freedom in the U.S."), and Shurtleff
    himself (who would present a Boston-centric historical overview).
    Believing that its response to the plaintiffs' first flag-raising
    request    was   self-explanatory,     the   City   chose   not   to   respond
    further.
    About a year later, the City embodied its past policy
    and practice in a written Flag Raising Policy.                    This policy
    includes seven flag raising rules, the first of which forbids the
    "display [of] flags deemed to be inappropriate or offensive in
    nature or those supporting discrimination, prejudice, or religious
    movements."
    On July 6, 2018 — roughly three months before the City
    adopted its written Flag Raising Policy — the plaintiffs sued the
    City in the federal district court, seeking injunctive relief, a
    declaratory judgment, and money damages.            Three days later, they
    moved for a preliminary injunction.          The district court denied the
    plaintiffs' motion, see Shurtleff v. City of Bos. (Shurtleff I),
    
    337 F. Supp. 3d 66
     (D. Mass. 2018), and we affirmed, see Shurtleff
    v. City of Bos. (Shurtleff II), 
    928 F.3d 166
     (1st Cir. 2019).             Back
    in   the   district   court,   the    parties   conducted    discovery    and
    eventually cross-moved for summary judgment.           The district court
    heard arguments and, in a comprehensive rescript, granted the
    - 9 -
    City's    motion    and   denied    the    plaintiffs'       cross-motion.      See
    Shurtleff III, 
    2020 WL 555248
    , at *6. This timely appeal followed.
    II. ANALYSIS
    The plaintiffs assign error to the district court’s
    grant of summary judgment.                Specifically, they challenge the
    court's holding that the City's display of third-party flags on
    the City Hall flagpole constitutes government speech, not subject
    to most First Amendment restrictions.                In their view, the City's
    flagpoles comprise a public forum, thus consigning the City's
    content-based restriction of plaintiffs' speech to strict scrutiny
    (which they say the restriction cannot pass).                     Relatedly, they
    contend that the City's permitting process for the raising of
    third-party       flags   vests     in     government    officials       unbridled
    discretion to approve and deny protected speech and, thus, imposes
    an unconstitutional prior restraint on speech.                      Finally, they
    contend    that    the    City's    refusal     to     fly    a   religious    flag
    transgresses       both   the     Establishment       Clause      and   the   Equal
    Protection Clause.
    The City urges us to reject each and all of these
    contentions and simply to affirm the district court's rulings.                   It
    is joined by a group of amici, who have filed a helpful brief in
    support of the judgment below.
    We afford de novo review to a district court's entry of
    summary judgment.         See Dávila v. Corporación De P.R. Para La
    - 10 -
    Difusión Pública, 
    498 F.3d 9
    , 12 (1st Cir. 2007).                    In conducting
    this tamisage, we assess the facts in the light most flattering to
    the nonmovants (here, the plaintiffs) and draw all reasonable
    inferences     to    their    behoof.      See    
    id.
        Summary       judgment    is
    appropriate only when the record demonstrates that there is no
    genuine issue as to any material fact and confirms that the movants
    are entitled to judgment as a matter of law.                        See Morelli v.
    Webster, 
    552 F.3d 12
    , 18 (1st Cir. 2009).               That cross-motions for
    summary judgment were simultaneously adjudicated by the district
    court does not alter the applicable standards of review.                          See
    Blackie v. Maine, 
    75 F.3d 716
    , 720-21 (1st Cir. 1996).
    With       these    parameters    in     place,     we    turn    to   the
    plaintiffs'         asseverational       array,     taking     their        arguments
    sequentially.        At the outset, though, we pause to say a few words
    about the relevance of our earlier opinion (Shurtleff II).
    A.    Our Earlier Opinion.
    We think it useful to center our Shurtleff II opinion
    within   the   preliminary      injunction        framework.        That    framework
    anticipates a four-part inquiry, see Corp. Techs., Inc. v. Harnett,
    
    731 F.3d 6
    , 9 (1st Cir. 2013); Ross-Simons of Warwick, Inc. v.
    Baccarat, Inc., 
    102 F.3d 12
    , 15 (1st Cir. 1996), requiring a
    district court to evaluate "the movant's likelihood of success on
    the merits; whether and to what extent the movant will suffer
    irreparable harm in the absence of preliminary injunctive relief;
    - 11 -
    the balance of relative hardships, that is, the hardship to the
    nonmovant if enjoined as opposed to the hardship to the movant if
    no injunction issues; and the effect, if any, that either a
    preliminary injunction or the absence of one will have on the
    public interest," Ryan v. U.S. Immig. & Customs Enf't, 
    974 F.3d 9
    ,
    18 (1st Cir. 2020).      Among these four factors, "[t]he movant's
    likelihood of success on the merits weighs most heavily in the
    preliminary injunction calculus." 
    Id.
     As we have explained, "[i]f
    the movant 'cannot demonstrate that he is likely to succeed in his
    quest, the remaining factors become matters of idle curiosity.'"
    
    Id.
     (quoting New Comm Wireless Servs., Inc. v. SprintCom, Inc.,
    
    287 F.3d 1
    , 9 (1st Cir. 2002)).
    In   Shurtleff    I,     the     district   court   denied   the
    plaintiffs' threshold motion for a preliminary injunction.             See
    377 F. Supp. 3d at 79.     The court determined, among other things,
    that the plaintiffs had not shown a likelihood of succeeding on
    the merits of their claims.      See id. at 78.   On appeal, we affirmed
    this determination, concluding that the district court's appraisal
    was not an abuse of discretion.          See Shurtleff II, 928 F.3d at
    171.
    The fact that Shurtleff II upheld the district court's
    determination that the plaintiffs were unlikely to prevail on the
    same claims that they now pursue is not determinative of either
    the issues that were before the district court in Shurtleff III or
    - 12 -
    the issues that confront us here.   There is, after all, a salient
    distinction between a decision granting or denying a preliminary
    injunction and a final decision on the merits (such as the entry
    of summary judgment).    At the preliminary injunction stage, "an
    inquiring court need not conclusively determine the merits of the
    movant's claim; it is enough for the court simply to evaluate the
    likelihood vel non that the movant ultimately will prevail on the
    merits."   Ryan, 974 F.3d at 18.
    Here, however, the appealed decision is one on the
    merits.    In Shurtleff III, the district court had to determine
    whether the City had shown that there were no genuine issues of
    material fact and, if so, that it was entitled to judgment as a
    matter of law.   See Morelli, 
    552 F.3d at 18
    .   Moreover, the court
    had to make this determination on a record that was considerably
    better developed than the record available to it at the preliminary
    injunction stage.   See Univ. of Tex. v. Camenisch, 
    451 U.S. 390
    ,
    395-96 (1981).   Thus, our decision in Shurtleff II, which was at
    most a validation of the district court's prediction of probable
    outcomes, see Jimenez Fuentes v. Torres Gaztambide, 
    807 F.2d 236
    ,
    238 (1st Cir. 1986), could inform the district court's subsequent
    summary judgment decision but could not control it, see Univ. of
    Tex., 
    451 U.S. at 395
    .
    - 13 -
    Shurtleff II relates to the current appeal in the same
    way.   That decision, therefore, does not determine the outcome of
    this merits appeal.    See 
    id.
       We proceed accordingly.
    B.   The Free Speech Claims.
    The plaintiffs' most loudly bruited argument is that the
    Free Speech Clause of the First Amendment does not permit the City
    to display a plethora of third-party flags in front of City Hall
    while refusing to display the Christian Flag proffered by the
    plaintiffs.   The district court determined that this group of
    claims was foreclosed by the government speech doctrine, see
    Shurtleff III, 
    2020 WL 555248
    , at *5, and so do we.
    The proposition that the plaintiffs' free speech claims
    rise or fall on the classification of the challenged speech is
    uncontroversial.      Even   though   the   First   Amendment   restricts
    government regulation of private speech in government-designated
    public forums, such restrictions do not apply to government speech.
    See Pleasant Grove City v. Summum, 
    555 U.S. 460
    , 467 (2009) ("The
    Free Speech Clause restricts government regulation of private
    speech; it does not regulate government speech."); Walker v. Tex.
    Div., Sons of Confederate Veterans, Inc., 
    576 U.S. 200
    , 215 (2015)
    ("[When] the State is speaking on its own behalf, the First
    Amendment strictures that attend the various types of government-
    established forums do not apply.").         Here, the classification of
    the speech in question is pivotal — but before attempting to
    - 14 -
    resolve this classification inquiry, we map the relevant contours
    of the government speech doctrine.
    Two cases chiefly inform the configuration of this map.
    In Summum, the Supreme Court considered whether "the Free Speech
    Clause of the First Amendment entitles a private group to insist
    that a municipality permit it to place a permanent monument in a
    city   park    in   which    other    donated    monuments   were    previously
    erected."       
    555 U.S. at 464
    .   The   respondent,    a    religious
    organization, sought leave from the city to erect a monument that
    would contain "the Seven Aphorisms of SUMMUM," which the respondent
    said would be similar "in size and nature to the Ten Commandments
    monument" then in place at the city park.             
    Id. at 465
    .     The city
    denied the respondent's request, and the respondent sued (alleging
    an abridgment of the right to free speech).              See 
    id. at 465-66
    .
    The Court upheld the city's decision, ruling that because the
    display of "a permanent monument in a public park . . . is best
    viewed as a form of government speech," such a display is "not
    subject to scrutiny under the Free Speech Clause."              
    Id. at 464
    .
    In determining that the placement of such a monument in
    a city-owned park constituted government speech, the Summum Court
    relied primarily on three factors.              First, the Court focused on
    the history of governmental use of monuments, explaining that
    "[g]overnments have long used monuments to speak to the public"
    and that "[w]hen a government entity arranges for the construction
    - 15 -
    of a monument, it does so because it wishes to convey some thought
    or instill some feeling in those who see the structure."           
    Id. at 470
    .   Second, the Court considered whether the message conveyed by
    the monuments would be ascribed to the government.            
    Id. at 471
    .
    The Court concluded that, in the city-park context, "there is
    little chance" that observers will fail to identify the government
    as the speaker.     
    Id.
       Third, and finally, the Court considered the
    fact that the municipality "effectively controlled" the messages
    sent   by   the   monuments   because   it   exercised   "final   approval
    authority over their selection."        
    Id. at 473
    .      Giving weight to
    these factors, the Court determined that the erection of privately
    donated monuments in a city park constituted government speech.
    See 
    id. at 472-73
    .
    A few years later, the Court revisited the government
    speech doctrine.     In Walker, the issue was whether the rejection
    of a "specialty license plate design featuring a Confederate battle
    flag" by the Texas Department of Motor Vehicles "violated the
    Constitution's free speech guarantees."            576 U.S. at 203-04.
    Concluding that specialty license plates convey government speech,
    the Court held that Texas was "entitled to refuse to issue plates"
    that featured the proffered design.          Id. at 219-20.   In reaching
    this conclusion, the Court again employed the three-factor test
    developed in Summum.
    - 16 -
    The Walker Court began by examining the history of the
    use of the medium by the government, then inquired into how closely
    the public identified the medium with the government, and went on
    to assay the degree of control the government maintained over the
    message conveyed.   See id. at 210-13.    In traveling down this path,
    the Court first found that license plates "long have communicated
    messages from the States."     Id. at 211.      Next, it found that the
    public reasonably interprets license plates as conveying a message
    on the state's behalf both because the plates bear "the name
    'TEXAS' in large letters" and because the state mandates vehicle
    owners to display the plate, owns all license plate designs, and
    dictates the manner in which vehicle owners may dispose of the
    plates.   Id. at 212.      Finally, the Court found that the state
    "effectively controlled" the messages conveyed on the license
    plates because it retained "final approval authority."           Id. at
    213.   These three factors, taken together, led inexorably to the
    conclusion   that   the   challenged   speech   constituted   government
    speech.   See id.
    The three-part Summum/Walker test is controlling here.
    Mindful that the Court has indicated that Walker "likely marks the
    outer bounds of the government-speech doctrine," Matal v. Tam, 
    137 S. Ct. 1744
    , 1760 (2017), we turn to whether the speech at issue
    falls within those bounds.
    - 17 -
    We start by looking at the historical use of flags by
    the government.   The parties do not gainsay that governments have
    used flags throughout history to communicate messages and ideas.
    See, e.g., W. Va. State Bd. of Educ. v. Barnette, 
    319 U.S. 624
    ,
    632 (1943) ("The use of an emblem or flag to symbolize some system,
    idea, institution, or personality, is a short cut from mind to
    mind."); Griffin v. Sec'y of Veterans Affs., 
    288 F.3d 1309
    , 1324
    (Fed. Cir. 2002) ("We have no doubt that the government engages in
    speech when it flies its own flags over a national cemetery, and
    that its choice of which flags to fly may favor one viewpoint over
    another.").   Flags themselves have the capacity to communicate
    messages pertaining to, say, a government's identity, values, or
    military strength.   See Shurtleff II, 928 F.3d at 173 n.4. Cf.
    Summum, 
    555 U.S. at 470
     ("Governments have long used monuments
    . . . to remind their subjects of their authority and power[,]
    . . . to commemorate military victories and sacrifices and other
    events of civic importance [or] to convey some thought or instill
    some feeling in those who see the structure.").     That a government
    flies a flag as a "symbolic act" and signal of a greater message
    to the public is indisputable.   See Shurtleff II, 928 F.3d at 173.
    With respect to the issue of whether an observer would
    attribute the message of a third-party flag on the City's third
    flagpole to the City, we found it likely the last time around that
    such an attribution would take place.     See id.     The record has
    - 18 -
    since evolved, and these evolutionary changes bolster our earlier
    conclusion.   As we previously noted, an observer would arrive in
    front of City Hall, "the entrance to Boston's seat of government."
    Id. at 174.   She would then see a city employee replace the city
    flag with a third-party flag and turn the crank until the third-
    party flag joins the United States flag and the Massachusetts flag,
    both "powerful governmental symbols," in the sky (eighty-three
    feet above the ground).     Id.    A faraway observer (one without a
    view of the Plaza) would see those three flags waiving in unison,
    side-by-side, from matching flagpoles.
    That the third-party flag is part of a broader display
    cannot be understated.     As the Summum Court explained, the manner
    in which speech is presented, including the incorporation of other
    monuments in the vicinity, changes the message communicated.     See
    
    555 U.S. at 477
    .   Here, the three flags are meant to be — and in
    fact are — viewed together.        The sky-high City Hall display of
    three flags flying in close proximity communicates the symbolic
    unity of the three flags.         It therefore strains credulity to
    believe that an observer would partition such a coordinated three-
    flag display (or a four-flag display if one counts the POW/MIA
    flag) into a series of separate yet simultaneous messages (two
    that the government endorses and another as to which the government
    disclaims any relation).    Cf. Summum, 
    555 U.S. 471
     ("It certainly
    is not common for property owners to open up their property for
    - 19 -
    the installation of permanent monuments that convey a message with
    which   they   do   not    wish    to    be    associated.").      Although    the
    plaintiffs might perhaps make the case that a lone Christian Flag,
    nowhere near City Hall, would be seen as devoid of any connection
    to a government entity, a City Hall display that places such a
    flag next to the flag of the United States and the flag of the
    Commonwealth of Massachusetts communicates a far different message
    to an observer:     that the City flies all three flags.
    The plaintiffs demur, insisting that an observer, in
    these circumstances, would not interpret a third-party flag as a
    message from the City.           This demurrer is premised on the notion
    that the question of whether expression is likely to be viewed as
    government     speech     must    be    answered    from   the   viewpoint    of   a
    "reasonable and informed" observer.              Building to a crescendo, the
    plaintiffs posit that a reasonable and informed observer not only
    would see the flag, but also would take note of the intricacies of
    the administrative process leading up to its display.                Stripped of
    rhetorical flourishes, the plaintiffs ask us to consider the
    perspective of an observer who — in their words — knows:
    (1) that the City's open invitation policy and
    practice         "seeks        to       accommodate     all
    applications seeking to take advantage of the
    City of Boston's public forums" . . .; (2)
    that the City permits private organizations
    - 20 -
    temporarily to raise their flags . . . as a
    "substitute" for the government's flag; (3)
    that the City has approved at least 284 flag
    raising events . . .; (4) that during the year
    preceding Camp Constitution's application the
    City approved an average of over three flag
    raisings per month; (5) that prior to Camp
    Constitution's      application,        flag       raising
    denials were exceedingly rare, and that Rooney
    had never denied a flag raising request; (6)
    that the City will allow essentially any event
    to take place on City Hall Plaza; and (7) that
    the City does not even review the content of
    the   substitute    flags   .   .   .    (emphasis      in
    original).
    Relatedly, the plaintiffs insist that the messages of the third-
    party flags cannot be attributed to the City because "Rooney swore
    he had no knowledge of anyone's ever believing the City has
    endorsed or adopted the message of a private organization that was
    allowed access to the flag raising forum."             An observer armed with
    this information, the plaintiffs say, would not attribute the
    third-party-flag speech to the City.
    The   plaintiffs'    conception         of     a   "reasonable   and
    informed" observer is not plucked from thin air.               Justice Souter,
    - 21 -
    concurring in Summum,      advocated for a    standard based on the
    reaction of a "reasonable and fully informed observer."      
    555 U.S. at 487
     (Souter, J., concurring).         The Court did not explicitly
    adopt this standard, but has nonetheless focused on the physical
    attributes of the speech and general information about the locus
    at which the speech takes place.   In Summum, for example, the Court
    considered what "persons who observe" such monuments see, 
    id. at 471
    , and added that most people know that parks are government
    property, 
    id. at 472
     ("Public parks are often closely identified
    in the public mind with the government unit that owns the land.").
    So, too, the Walker Court considered the physical attributes of
    the speech visible to "persons who observe" license plates, 576
    U.S. at 212 ("The governmental nature of the plates is clear from
    their faces . . . ."), as well as widely available information
    about license plates, id. ("[T]he State requires Texas vehicle
    owners to display license plates, and every Texas license plate is
    issued by the State . . . .      Texas also owns the designs on its
    license plates . . . .      And Texas dictates the manner in which
    drivers may dispose of unused plates.").      The City's treatment of
    third-party flags satisfies the standard that the Supreme Court
    has set for attribution:    an observer not only would see the third-
    party flag flying with two government flags in front of a building
    labeled "Boston City Hall" but also would reason that the building
    - 22 -
    is a government building and that the imposing flagpoles located
    on that property are owned and dressed by the City.2
    The plaintiffs have another string to their bow.                 They
    argue that the Summum/Walker framework is inapplicable because the
    third-party flags that the City flies lack the permanence of the
    monuments in Summum.      We rejected this same argument in Shurtleff
    II, 928 F.3d at 175, and the plaintiffs have advanced no compelling
    reason for us to revisit the matter.           To our way of thinking, the
    decisive datum is that the Walker Court explicitly disavowed any
    suggestion     that    permanence    is    a   prerequisite    for    finding
    government speech.      See 576 U.S. at 213-14.
    We    turn    next   to   the   question   of   whether    the   City
    maintains control over the messages conveyed by the third-party
    2 We add, moreover, that even if we were prepared to adopt a
    "reasonable and informed observer" standard, such a standard would
    be satisfied here. See Shurtleff II, 928 F.3d at 173 n.5. It is
    the manner and circumstances in which a third-party flag is
    displayed, together with the logical inferences that a reasonable
    and informed observer would likely draw based on available
    information, that lead to a conclusion that the third-party-flag
    speech can be attributed to the government.
    Relatedly, Justice Souter's concurrence in Summum warned
    primarily against the deployment of categorical rules in
    determining what constitutes government speech. Summum, 
    555 U.S. at 487
     (Souter, J., concurring).     Contrary to the plaintiffs'
    formulation of the "reasonable and informed observer" standard,
    neither Justice Souter's concurrence nor any other cited opinion
    has suggested that such an observer would necessarily know things
    like the City's regulations for flag-raising or the decisionmaking
    trends of a specific government employee. Absent any vestige of
    precedential support, we decline the plaintiffs' invitation to
    adopt and apply a newly minted standard.
    - 23 -
    flags.       The City has instituted procedures to ensure both that it
    is aware of all flags flown and that such flags display approvable
    messages.           It   is    undisputed      that   "[i]nterested        persons    and
    organizations must apply to the City for a permit before they can
    raise    a    flag       on   this    flagpole,"      and    that    the   flag-raising
    guidelines expressly require the City's permission to fly a third-
    party flag.         Shurtleff II, 928 F.3d at 174.                  And in order for a
    flag-raising request to secure approval, Rooney must review the
    request       to    determine        whether    the    proposed       flag-raising     is
    consistent with the City's message, policies, and practices.                          Cf.
    Summum,       
    555 U.S. at 472
       (finding         government     speech    when
    "[g]overnment decisionmakers select the monuments that portray
    what they view as appropriate for the place in question, taking
    into account such content-based factors as esthetics, history, and
    local culture"); Walker, 576 U.S. at 213 (finding control when
    "[t]he Board must approve every specialty plate design proposal
    before the design can appear on a Texas plate").
    What is more, the City limits physical access to the
    flagpole:      the flagpole is restricted government property, and the
    City restricts access to                it by providing          only parties whose
    requests are approved with a hand crank.                    All in all, the decision
    to fly a flag falls squarely on the City, and not on any other
    entity or person.             This final approval authority means that when
    a third-party flag flies over City Hall, it flies only because the
    - 24 -
    City chose to fly it.             And in reserving this final approval
    authority, the City "has 'effectively controlled' the messages
    conveyed" in the flag display.            Id. (quoting Johanns v. Livestock
    Mktg. Ass'n, 
    544 U.S. 550
    , 560 (2005)).
    The    plaintiffs     argue     that     the   type    of    government
    practices   that    led     the   Court   in   Summum      and    Walker   to   find
    government control are not present here.               They note, for example,
    that the Summum Court observed that the government "took ownership
    of [the] monument" and that "[a]ll rights previously possessed by
    the monument's donor [were] relinquished."                 
    555 U.S. at 473-74
    .
    They also note that, in Walker, the state owned the designs that
    were on all specialty license plates, issued all state plates, and
    dictated how a driver may dispose of a plate.                    576 U.S. at 212.
    Here, by contrast, the City does not require a private organization
    that seeks to raise a flag to surrender ownership of that flag,
    nor does it require that a flag bear any particular design or logo.
    This argument lacks force.             The government's ownership
    of a monument or a design are relevant to the "attribution" prong
    of the Summum/Walker test — not to the "control" prong.                          See
    Walker, 576 U.S. at 212; Summum, 
    555 U.S. at 473-74
    .                     The latter
    prong   instead     turns    on   whether      the   government      "effectively
    control[s]" the message conveyed through selection.                     See Summum,
    
    555 U.S. at 473
     (quoting Johanns, 
    544 U.S. at 560-61
    ).                   The City's
    - 25 -
    final approval authority over all third-party flags evinces choice
    and selection and, thus, suffices to show effective control.
    Struggling to undermine the finding of control, the
    plaintiffs highlight three pieces of evidence uncovered during
    pretrial     discovery   (and     not   available    at   the     preliminary
    injunction stage):       first, until the plaintiffs came along, the
    City had not previously denied a flag-raising request; second,
    Rooney's customary practice was not to ask to see a proposed flag
    before     approving   such   a   request;   and     third,     although    the
    preliminary    injunction     record    previously    noted     only    fifteen
    instances of flag-raisings, the expanded record reveals that the
    City had approved 284 requests.         The plaintiffs submit that these
    freshly unearthed facts demonstrate that the City did not exercise
    meaningful control over the message conveyed by third-party flags.
    We do not agree.
    We find the rate of rejection unpersuasive because the
    exercise of the authority to reject is necessarily case-specific
    and limited by the kinds of requests the City receives.                Since the
    City had never rejected a request, the flag-raisings in the record
    are, in effect, a record of the requests received.              Every request
    has been for the flag of a country, civic organization, or secular
    cause.   That potential applicants have successfully self-selected
    and offered a narrow set of acceptable secular designs cannot be
    evidence that the City is open to fly any flag.
    - 26 -
    The limited kinds of unique flags and the repeated
    requests to fly the same flags also help to explain Rooney's
    practice.   Some of the flags were no doubt familiar to him and, at
    any rate, a request to fly a flag includes a short description of
    the flag.       Because Rooney recognizes the names            of sovereign
    nations, because the City had seen most, if not all, of these flags
    in previous years, and because in twelve years no person had
    requested to fly anything that was not the flag of a country, civic
    organization,     or   secular   cause,    a   short   description    of   each
    proposed flag was sufficient for Rooney's purposes.                  But once
    Rooney received a request for a flag he did not recognize as
    falling within an acceptable secular category — the Christian Flag
    — he demanded that he see it.
    The   greater    number   of       flag-raisings   is     likewise
    insufficient to ground a finding that the City does not control
    the flagpole.     The Walker Court was clear that the number of flags
    — or messages — is not dispositive.            576 U.S. at 214.      Here, the
    Walker's Court logic applies because the number of flags approved
    by the City is not evidence of universal access to the flagpole.
    After all, the group of third-party flags raised over City Hall
    during the twelve-year period is not a random assortment.                  Each
    flag represents a country, civic organization, or secular cause.
    Instead of evincing a lack of control, the greater number of flag-
    raisings reveals a pattern that supports the City's claim that it
    - 27 -
    approves only flags that it deems "consistent with the City's
    messages, policies, and practices."
    In this context, the Supreme Court has not laid out an
    elaborate    protocol    for    finding    effective   control.            Broadly
    speaking, it is the City's "select[ion] [of] those [flags] that it
    wants to display for the purpose of presenting the image of the
    City that it wishes to project" that establishes City control over
    the message conveyed.         Summum, 
    555 U.S. at 473
    .        In the case at
    hand, Rooney's approval practices have not been shown to be a
    rubber stamp.       There is nothing remarkable about the fact that
    some flag descriptions may trigger further review, while others do
    not.     Wherever the line falls, that a line exists is evidence of
    "selective receptivity."        See 
    id. at 471
    .    That selectivity exists
    here, and it is a selectivity born out of a concern for the City's
    image.      The record, taken as a whole, plainly shows a city
    conscious of the message that it flies on the third flagpole and
    an accompanying selectivity to tailor that message to the City's
    desired    image.       See    
    id.
        Accordingly,     each   of     the    three
    Summum/Walker    factors      supports    the   conclusion    that    the    City
    engages in government speech when it decides which flags to display
    in front of City Hall.
    The plaintiffs demur.         They deride this classification
    of the City's speech, arguing vehemently that the City does not
    engage in expressive activity through these third-party flags
    - 28 -
    because it has designated the third flagpole as a forum for private
    speech.       In     support,   they     offer    two   arguments.          First,    the
    plaintiffs say that the City explicitly opened the flagpole to
    private expression.        Specifically, they point to the third page of
    the City's paper event application form, which states that the
    City "seeks to accommodate all applicants seeking to take advantage
    of the City of Boston's public forums."                    The plaintiffs suggest
    that the phrases "all applicants" and "public forums" transmogrify
    the third flagpole into a government-designated public forum.
    Second,      and    relatedly,     the       plaintiffs    argue     that    the     City
    implicitly opened the flagpole for public discourse because the
    record now shows that the City had granted flag-raising permission
    284 times without ever denying an earlier request.
    These two arguments coalesce into a single theme — but
    it is a theme that gains the plaintiffs no traction.                   We previously
    rejected the first of these arguments because a conclusion that
    the   City    has     designated       the   flagpole     as   a   public   forum    "is
    precluded by our government-speech finding."                       Shurtleff II, 928
    F.3d at 175.        As we explain below, that rationale still withstands
    scrutiny — and even under traditional public-forum analysis, the
    plaintiffs' asseverational array lacks force.
    The     government       creates    a     public     forum     "only    by
    intentionally         opening      a     nontraditional        forum    for     public
    discourse."         Cornelius v. NAACP Legal Def. & Edu. Fund, Inc., 473
    - 29 -
    U.S. 788, 802 (1985).         Government inaction or permission for
    limited discourse cannot establish a public-forum designation.
    Id.     To determine if the City has converted the flagpole into a
    public forum, we look to the City's "policy and practice" and also
    may consider "the nature of the [flagpole] and its compatibility
    with expressive activity."       Id.   "We will not find that a public
    forum has been created in the face of clear evidence of a contrary
    intent," nor will we make such a finding "when the nature of the
    property is inconsistent with expressive activity."           Id. at 804.
    At the preliminary injunction stage, we rejected the
    plaintiffs' argument that the City's "public forum[]" incantation
    rendered the flagpole a public forum because the record contained
    clear evidence that the City did not intend to open the flagpole
    to public discourse.        Shurtleff II, 928 F.3d at 176.           On the
    enlarged record now before us — which shows that the City over
    time has approved 284 requests and has never denied any request
    other than the plaintiffs' request — our conclusion remains the
    same.
    The record is pellucid that the City is not receptive to
    any and all proposed flag designs.           As we previously indicated,
    the City controls which third-party flags are flown from the third
    flagpole. A flag-raising is approved only after Rooney "screen[s]"
    a   proposed   flag   for   "consisten[cy]    with   the   City's   message,
    policies, and practices" and provides his final approval.               Id.;

    cf. Perry Educ. Ass'n v. Perry Loc. Educators' Ass'n, 
    460 U.S. 37
    ,
    47   (2001)   (finding   that     school's      mail   system     had    not   been
    designated as a public forum when school principal had to grant
    permission    to   access   system).           Furthermore,      all    284    flags
    previously flown were flags of countries, civic organizations, or
    secular causes.     That the City had not rejected prior requests is
    insufficient to conclude that the City accepts any and all flags
    because the record shows that the City had criteria for approval
    that limited flagpole access and that all flags flown satisfied
    those criteria.     Cf. Cornelius, 473 U.S. at 804-05 (declining to
    find designated public forum notwithstanding lack of evidence
    showing how many organizations had been denied permission because
    admission criteria evidenced selective access).                 Here, the City's
    permission    procedures       evince   selective      access    to     the    third
    flagpole, and "[t]he government does not create a designated public
    forum when it does no more than reserve eligibility for access to
    the forum to a particular class of speakers, whose members must
    then, as individuals, 'obtain permission.'"              Ark. Edu. Television
    Comm'n   v.   Forbes,    
    523 U.S. 666
    ,    679    (1998).         The    City's
    restrictions demonstrate an intent antithetic to the designation
    of a public forum, and those restrictions adequately support the
    conclusion that the City's flagpole is not a public forum.                       See
    Cornelius, 473 U.S. at 803.

    That ends this aspect of the matter.    Because the City
    engages in government speech when it raises a third-party flag on
    the third flagpole at City Hall, that speech is not circumscribed
    by the Free Speech Clause.    See Walker, 576 U.S. at 215; Summum,
    
    555 U.S. at 467
    .    The City is therefore "entitled" to "select the
    views that it wants to express."         Summum, 
    555 U.S. at 467-68
    (internal citations omitted).    This entitlement includes both the
    right to decide not to speak at all and the right to disassociate
    itself from speech of which it disapproves.     See Mech v. Sch. Bd.
    of Palm Beach Cnty., 
    806 F.3d 1070
    , 1074 (11th Cir. 2015); Downs
    v. L.A. Unified Sch. Dist., 
    228 F.3d 1003
    , 1012 (9th Cir. 2000).
    Here, the City exercised those rights by choosing not to
    fly the plaintiffs' third-party flag.       In the City's view, this
    choice allows it more appropriately to celebrate the diversity and
    varied communities within Boston.    Should the citizenry object to
    the City's secular-flag policy or to its ideas about diversity,
    the voters may elect new officials who share their concerns.     See
    Summum, 
    555 U.S. at 468-69
    ; Bd. of Regents of Univ. of Wisconsin
    Sys. v. Southworth, 
    529 U.S. 217
    , 235 (2000); Walker, 
    576 U.S. 200
    , 207.     After all, it is the electorate and the political
    process that constrains the City's speech, not the Free Speech
    Clause.   See Summum, 
    555 U.S. at 468-69
    .    Consequently, we uphold
    the district court's entry of summary judgment in favor of the
    - 32 -
    City on all of the plaintiffs' free speech claims.3             See Shurtleff
    III, 
    2020 WL 555248
    , at *6.
    C.    The Establishment Clause Claim.
    The fact that the City is engaging in government speech
    does not relieve it from the obligation to comport with the
    Establishment Clause.        Summum, 
    555 U.S. at 468
    .          The plaintiffs
    assert that the City has failed to satisfy this obligation for two
    reasons.     First, they assert that the City discriminated between
    religion and nonreligion by excluding their proffered flag while
    continuing to fly non-religious flags.             Second, they assert that
    the   City   discriminated     between    religions    by   excluding   their
    Christian Flag while flying flags that contain other religious
    imagery.     As examples, the plaintiffs cite the City's own flag,
    the Turkish flag, the Portuguese flag, and the Bunker Hill flag.
    The City's conduct in this regard, the plaintiffs say, is not only
    discriminatory but also demonstrates hostility toward religion.
    The "touchstone" for Establishment Clause claims "is the
    principle     that     the   'First    Amendment    mandates     governmental
    3 This ruling extends, of course, to the plaintiffs'
    "unbridled discretion" claim. Both the plaintiffs' articulation
    of that claim and the authority that they present in support of it
    presuppose the existence of a public forum. Our conclusion that
    the flagpole is not a public forum therefore defenestrates the
    plaintiffs' claim. See Widmar v. Vincent, 
    454 U.S. 263
    , 267-68,
    267 n.5 (1981) (noting that university's constitutional obligation
    to justify prior restraint on speech arises from its designation
    of its campus as public forum and would not exist otherwise).

    neutrality between religion and religion, and between religion and
    nonreligion.'"         McCreary Cnty. v. ACLU of Ky., 
    545 U.S. 844
    , 860
    (2005) (quoting Epperson v. Arkansas, 
    393 U.S. 97
    , 104 (1968)).
    The government does not act neutrally when its "ostensible object
    is to take sides."           
    Id.
        Accordingly, the government "cannot act
    in   a       manner   that    passes   judgment      upon    or   presupposes     the
    illegitimacy of religious beliefs and practices."                      Masterpiece
    Cakeshop Ltd. v. Col. Civ. Rights Comm'n, 
    138 S. Ct. 1719
    , 1731
    (2018).
    Starting     from   this    baseline,   we    turn   first   to   the
    allegations of discrimination between religion and nonreligion.
    At the outset, we take note that the plaintiffs' Establishment
    Clause claim is scantily developed:                 they have neither identified
    any evidence supporting a claim of hostility nor advanced any
    serious legal argument for such a claim.                    The plaintiffs merely
    recite the general neutrality obligation that the Establishment
    Clause imposes upon the City, failing to articulate any reason why
    this obligation requires the City to display their religious flag.4
    The plaintiffs' sparse treatment of their Establishment
    4
    Clause claim suggests that this case, at its core, is not an
    Establishment Clause case. This suggestion is bolstered by the
    fact that the type of hostility argument conceptualized by the
    plaintiffs appears to draw its essence from Supreme Court decisions
    involving the Free Exercise Clause and applying the strict-
    scrutiny standard. See, e.g., Trinity Lutheran Church of Columbia,
    Inc. v. Comer, 
    137 S. Ct. 2012
     (2017) (holding that exclusion of
    church from otherwise available public program on account of
    religious   status   violates    Free   Exercise   Clause   despite
    - 34 -
    The   exclusion        of    religious    entities   from   a    public
    program, without more, does not violate the Establishment Clause.
    See Carson ex rel. O.C. v. Makin, 
    979 F.3d 21
    , 49 (1st Cir. 2020).
    Nor is proof of such exclusion evidence of hostility towards
    religion.    See 
    id.
       Here, moreover, the record does not give rise
    to any suggestion that the City created the flag-raising program
    with the goal of inhibiting religion.                 Cf. Rosenberger v. Rector
    & Visitors of Univ. of Va., 
    515 U.S. 819
    , 840 (1995) (finding
    governmental      program     to    be     "neutral     toward   religion"     when
    government did not "create[] it to advance religion or adopt[]
    some ingenious device with the purpose of aiding a religious
    cause"); McCreary, 
    545 U.S. at 860
     (requiring proof of government
    "purpose" to favor one side over the other).                   In fact, the City
    went the extra mile:        to help avoid any such impression, it offered
    the plaintiffs the option of hosting an event alongside the
    flagpoles so as to permit the plaintiffs to continue to practice
    and share their religion (just as they would had the City granted
    their   flag-raising    request).           Under     these   circumstances,    the
    government's establishment concerns); Espinoza v. Montana Dep't of
    Revenue, 
    140 S. Ct. 2246
     (2020) (same where government excluded
    school based on religious character of the school). In the case
    at hand, the plaintiffs do not advance a cognizable free exercise
    claim but, rather, seek the application of a concept of hostility
    to religion not typically applied to Establishment Clause claims
    like this one. Seen in this light, the plaintiffs' theory fits
    awkwardly with precedent — an awkwardness that greatly diminishes
    the force of their claim.
    - 35 -
    City's   conduct       simply    cannot    be    construed      to      suggest   the
    disparagement     of    the     plaintiffs'     religion.       Cf.      Masterpiece
    Cakeshop, 
    138 S. Ct. at 1729
     (finding hostility toward religion
    when government "disparage[d]" plaintiff's religion "by describing
    it as despicable," "characterizing it as merely rhetorical," and
    comparing it "to defenses of slavery and the Holocaust").
    We add, moreover, that while the Establishment Clause
    may not require a secular-flag policy, the City "may act upon [its]
    legitimate concerns about excessive entanglement with religion" in
    administering its flag-raising program.                Eulitt ex rel. Eulitt v.
    Maine, Dep't of Educ., 
    386 F.3d 344
    , 355 (1st Cir. 2004); see also
    Carson ex rel. O.C., 979 F.3d at 35.             The City has presented just
    such a set of concerns in this case and, thus, has made a valid
    choice   to    remain    secular.        Shurtleff      himself      described    the
    Christian flag as "an important symbol of our country's Judeo-
    Christian     heritage."        Should    the   City    honor     the    plaintiffs'
    request, members of the audience would watch the Christian Flag
    join the flags of the United States and Massachusetts in front of
    the entrance of City Hall.            Such a display could be deemed to
    constitute a religious statement on the City's part.                        Cf. Am.
    Jewish Cong. v. City of Chicago, 
    827 F.2d 120
    , 128 (7th Cir. 1987)
    (noting that placement of religious display at city hall heightens
    Establishment Clause concerns because "every display . . . is
    implicitly marked with the stamp of government approval").                        And
    - 36 -
    such a perception would underscore the realistic nature of the
    City's belief that the flying of a flag would be an endorsement of
    the flag's message.     See Widmar v. Vincent, 
    454 U.S. 263
    , 274
    (1981)    (evaluating   whether    government   policy   confers   "any
    imprimatur of state approval on religious sects or practices").
    Our government-speech finding bolsters the conclusion
    that the City would be perceived to endorse the messages conveyed
    by the flags that it flies.       When a forum is open to all, it is
    doubtful that an observer "could draw any reasonable inference of
    [government] support" for a particular religion from religious
    speech alone.     
    Id. at 274
    , 274 n.14.     In such a situation, the
    City would not be seen as supporting religious goals.          See 
    id.
    Here, however, the City speaks for itself, one third-party flag at
    a time.   Because an observer would attribute the display's message
    to the City, see supra Part II(B), the powerful display of a single
    religion's flag    (in this case,     an "important symbol" of      the
    plaintiffs' religion) could signal the City's embrace of that
    religion.
    To complete the picture, it is worth noting that the
    Supreme Court has explicitly distinguished the religious character
    of long-standing religious monuments, symbols, and practices from
    that of newly erected or adopted ones.          See Am. Legion v. Am.
    Humanist Assoc., 
    139 S. Ct. 2067
    , 2085 (2019).       In relevant part,
    the American Legion Court reasoned that, with the passage of time,
    - 37 -
    "religiously expressive monuments, symbols, and practices can
    become embedded features of a community's landscape and identity,"
    such that the community "may come to value them without necessarily
    embracing their religious roots."                
    Id. at 2084
    .        In other words,
    a display of a religious symbol, over time, can "t[ake] on an added
    secular meaning."     
    Id. at 2089
    .         Long-standing monuments therefore
    enjoy "a strong presumption of constitutionality."                     
    Id. at 2085
    .
    This   presumption       does       not    apply,      though,    to     the
    plaintiffs' proposed religious-flag display.                     The City has never
    before   displayed    such     a    flag   and,        as   such,   this    pioneering
    elevation of an "important symbol" of the Christian heritage would
    come without the secular context or importance that the passage of
    time   may   have   afforded       other   displays.          The   raising     of    the
    Christian Flag thus would threaten to communicate and endorse a
    purely religious message on behalf of the City.                            Where that
    endorsement is as widely visible and accessible as it is here, and
    where the City could run the risk of repeatedly coordinating the
    use of government property with hierarchs of all religions, the
    City's   establishment    concerns         are    legitimate.         See     Lemon    v.
    Kurtzman, 
    403 U.S. 602
    , 615 (1971).              Accordingly, we conclude that
    the City's choice to refrain from endorsing a religion through the
    raising of a religious flag comports with the City's constitutional
    obligations.
    - 38 -
    This   leaves   the    plaintiffs'    claim   that   the   City's
    raising of certain flags that incorporate religious imagery while
    excluding    the    plaintiffs'      Christian     Flag    constitutes     an
    endorsement of certain religions over others and, thus, works a
    violation of the Establishment Clause.           "[A] flag that references
    religion by using religious symbols in part of its field is not
    itself a religious flag."         Shurtleff II, 928 F.3d at 177.       As the
    plaintiffs repeatedly emphasize, Rooney does not even look at the
    flag designs before granting most approvals.          And when he reviewed
    what an applicant described as the "Portuguese Flag," Rooney
    approved it because it stands for Portugal, the country, and not
    because it contained certain religious symbols.              For aught that
    appears, Rooney's decision to fly those country/entity flags that
    include religious imagery was one without a religious dimension.
    In a logical universe, then, the fact that Rooney elected to let
    the Flag of Portugal fly is manifestly insufficient to establish
    that the City is hostile to the plaintiffs' religion.5
    The short of it is that neutrality toward religion does
    not obligate the City to fly the Christian Flag on its third
    flagpole.    The City remains neutral where, as here, it wholly
    refrains from passing judgment on religion.               See McCreary, 545
    5 For substantially the same reasons, Rooney's decision to
    allow the hoisting of other flags incidentally containing
    religious imagery (such as the Turkish flag, the Bunker Hill flag,
    and the City's own flag) do not evince hostility toward religion.
    - 39 -
    U.S. at 876.    Consequently, we hold that no violation of the
    Establishment Clause occurred when the City elected not to fly the
    plaintiffs' Christian Flag.
    D.    The Fourteenth Amendment Claim.
    There is one last stop on our itinerary.       The plaintiffs
    submit   that   the    City's   conduct   amounts   to   content-based
    discrimination against their religious speech and, thus, violates
    the Equal Protection Clause.     The City counters that, because the
    flagpole is not a public forum and because the plaintiffs' First
    Amendment claims are futile, their equal protection claim fails as
    a matter of law.
    We pause to brush aside a procedural gambit.             The
    plaintiffs suggest that the City has waived any counter-argument
    to their equal protection claim.     This is magical thinking:     the
    City advanced the very same argument upon which it now relies at
    summary judgment.     No more was exigible to preserve the argument
    for appellate review.    See United States v. Lilly, 
    13 F.3d 15
    , 18
    (1st Cir. 1994).
    Turning to the merits of the claim, we start with the
    familiar proposition that the Equal Protection Clause demands that
    "all persons similarly situated should be treated alike."       City of
    Cleburne v. Cleburne Living Ctr., 
    473 U.S. 432
    , 439 (1985).         To
    establish an equal protection claim, a plaintiff must show that
    "(1) the person, compared with others similarly situated, was
    - 40 -
    selectively treated; and (2) that such selective treatment was
    based on impermissible considerations such as race, religion,
    intent to inhibit or punish the exercise of constitutional rights,
    or malicious or bad faith intent to injure a person."                   Davis v.
    Coakley, 
    802 F.3d 128
    , 132-33 (1st Cir. 2015).
    What we previously have said — that the City has been
    engaged in government speech not evocative of First Amendment
    protections and that the flagpole is not a public forum, see supra
    Part II (B) — sounds the death knell for the plaintiffs' equal
    protection claim.      The distinguishing feature of the speech cases
    in which the Supreme Court has found violations of the Equal
    Protection Clause is the existence of a public forum.                   See Perry
    Educ. Ass'n, 460 U.S. at 55; see, e.g., Police Dep't of Chicago v.
    Mosely, 
    408 U.S. 92
    , 96 (1972); Carey v. Brown, 
    447 U.S. 455
    , 461
    (1980).     Conversely, the Court has made nose-on-the-face plain
    that "on government property that has not been made a public forum,
    not   all   speech   is   equally   situated,       and   the   State   may   draw
    distinctions which relate to the special purpose for which the
    property is used."        Perry Educ. Ass'n, 460 U.S. at 55.              In the
    absence of a public forum — and we have found none here — the
    City's practice need only pass rational basis review.                    See id.
    Put   another   way,      the   practice     need    only   bear    a    rational
    relationship to some legitimate governmental purpose.                    See id.
    Here, such a purpose is evident in the celebration of Boston's
    - 41 -
    varied and diverse communities.      Consequently, the plaintiffs'
    equal protection claim fails.
    III. CONCLUSION
    We need go no further.       Like the district court, see
    Shurtleff III, 
    2020 WL 555248
    , at *6, we have taken the measure of
    the plaintiffs' claims and found them wanting. Hence, the judgment
    of the district court is
    Affirmed.
