Flags serve as important symbols. The U.S. flag is especially prominent, and it remains common for school children to salute this flag, which is sometimes displayed next to the state flag.
West Virginia State Board of Education v. Barnette (1943) has clearly established that school students cannot be forced to salute the flag against their convictions.
Court decisions, most notably in Texas v. Johnson (1989) and United States v. Eichman (1990), have affirmed the right of protestors to burn the flag in protest of governmental policies as an act of symbolic speech, with due regard for time, place, and manner restrictions. Tinker v. Des Moines Independent Community School District (1969) (in that case wearing black armbands to protest the Vietnam War) had previously extended some rights of symbolic speech to public school children.
Some flags, most notably a flag representing the Ku Klux Klan or the Confederate States of America, might represent or provoke violence, and many schools have banned such flags or other attempts at symbolic intimidation. In Melton v. Young (6th Cir. (1972), A federal court upheld a public-school ban on wearing Confederate flag clothing on the basis that it could be disruptive. Some schools have also banned symbols supporting the Black Lives Matter symbols on the basis that they might be too provocative (Pendharkar 2022). What about other flags or symbols?
Rainbow Pride flags have become a symbol of LGBTQ rights
Although U.S. embassies in 2014 began displaying the rainbow flag during LGBTQ week (Vile, 2024), more recently, a number of state legislatures have adopted measures to ban the display of the Pride, or Rainbow, Flag in schools or on other public properties. Although the symbol has symbolic roots that date back to the biblical book of Genesis (9:12-17) and beyond into the world of art and play (Rainbow Dash was a Pegasus pony portrayed with a rainbow tail), the multicolored LGBTQ rainbow flag, which was invented by Gilbert Baker of San Francisco, California, in 1978, has become a symbol of LGBTQ rights.
Although the flag is not, like some other symbols, associated with intimidation, it might well lead to provocative discussions about sexual identities, which some might consider to be inappropriate, especially for students in lower grades. In Mahmoud v. Taylor, 606 U.S. ____ (2025), the U.S. Supreme Court ruled that parents have the right under the free exercise of religion clause of the First Amendment to exempt their students from classroom presentations on gay marriage and trans students.
Gino Bulso, a Republican state representative from Brentwood, Tennessee, who sponsored a bill banning any flags on public or charter school properties, other than the U.S. or the state flag thus defended his proposal by saying that “A school should be a place where a child goes to learn, not a place where a child goes to be indoctrinated.” He further argued that the ban was further designed (perhaps like laws prohibiting or prescribing state-composed or state-mandated prayers) as a way to keep “authority figures from injecting into the classroom these political statements” (Shepherd 2023).
ACLU says banning pride flag alone is viewpoint discrimination
The American Civil Liberties Union has taken the position that banning the Pride Flag alone would be a form of viewpoint or content discrimination prohibited by such decisions as United States v. Grace (1983) or Reed v. Town of Gilbert (2015). Under the doctrine of government speech, it is not clear, however, whether this would apply to a law that banned all flags other than the national and state flags, especially in school settings that involve more impressionable students in a mandated setting.
In Shurtleff v. Boston, 596 U.S. ____ (2022), the Supreme Court ruled that a governmental entity, in this case Boston, that regularly allowed outside groups to fly their flag outside Boston City Hall, could not exclude a Christian flag, because earlier practice had established that such flags were acts of private, rather than public expression.
In 2025, the state of Utah banned the display of any flags on governmental properties other than the U.S. flag, the state flag, the POW flag, a military or Native American flag, or a school or municipal flag. In an attempt to indicate its own inclusiveness, the city of Salt Lake City, followed the earlier example of Boise City, Idaho, in incorporating the design of the rainbow flag into its city flag (Adams 2025) in a move that will likely be contested in court.
Much as there was once controversy over what constituted the burning of an American flag, there might be some interpretive difficulty in deciding on the meaning of the word “display.” Is, for example, a small image of a pride flag on a diversity inclusion statement that a teacher or counselor might display on a desk, a violation of the law?
If, as it appears, the legislation only bans actual flags, one might ask why a rainbow flag would be more provocative than the image of a pride flag emblazoned on a sweatshirt or jacket. Just as the law might be underinclusive, there is a chance that such a law might be overinclusive if it were to ban a teacher from displaying the flag of a country that was the subject of a history or geography class.
As in the case of other symbols that have been restricted, it seems likely that any legislation on the subject that is adopted will be subject to litigation, which would likely clarify such issues.
