I’m surprised no one has brought up the most direct precedent I can think of: Tinker v. Des Moines (1969).
A couple of Jehovah’s Witness kids John Tinker and Christopher Eckhardt (15 and 16 at the time) decided they’d wear black armbands to a public school in protest of the Viet Nam war.
The school district saw fit to suspend them. The kids filed suit on first amendment grounds, and the case went all the way to the Supreme Court.
Some excerpts from Justice Fortas’ opinion follow.
<<First Amendment rights, applied in light of the special characteristics of the school environment, are available to teachers and students. It can hardly be argued that either students or teachers shed their constitutional rights to freedom of speech or expression at the schoolhouse gate. This has been the unmistakable holding of this Court for almost 50 years. >>
<<In West Virginia v. Barnette, supra, this Court held that under the First Amendment, the student in public school may not be compelled to salute the flag. Speaking through Mr. Justice Jackson, the Court said:
“The Fourteenth Amendment, as now applied to the States, protects the citizen against the State itself and all of its creatures - Boards of Education not excepted. These have, of course, important, delicate, and highly discretionary functions, but none that they may not perform within the limits of the Bill of Rights. That they are educating the young for citizenship is reason for scrupulous protection of Constitutional freedoms of the individual, if we are not to strangle the free mind at its source and teach youth to discount important principles of our government as mere platitudes.” 319 U.S., at 637 . >>
<<The District Court concluded that the action of the school authorities was reasonable because it was based upon their fear of a disturbance from the wearing of the armbands. But, in our system, undifferentiated fear or apprehension of disturbance is not enough to overcome the right to freedom of expression. Any departure from absolute regimentation may cause trouble. Any variation from the majority’s opinion may inspire fear. Any word spoken, in class, in the lunchroom, or on the campus, that deviates from the views of another person may start an argument or cause a disturbance. But our Constitution says we must take this risk, Terminiello v. Chicago, 337 U.S. 1 (1949); and our history says that it is this sort of hazardous freedom - this kind of openness - that is [393 U.S. 503, 509] the basis of our national strength and of the independence and vigor of Americans who grow up and live in this relatively permissive, often disputatious, society.>>
<< In order for the State in the person of school officials to justify prohibition of a particular expression of opinion, it must be able to show that its action was caused by something more than a mere desire to avoid the discomfort and unpleasantness that always accompany an unpopular viewpoint. Certainly where there is no finding and no showing that engaging in the forbidden conduct would “materially and substantially interfere with the requirements of appropriate discipline in the operation of the school,” the prohibition cannot be sustained. Burnside v. Byars, supra, at 749.>>
<<It is also relevant that the school authorities did not purport to prohibit the wearing of all symbols of political or controversial significance. The record shows that students in some of the schools wore buttons relating to national political campaigns, and some even wore the Iron Cross, traditionally a symbol of Nazism. The order prohibiting the wearing of armbands did not extend to these. Instead, a particular symbol - black armbands worn to exhibit opposition to this Nation’s involvement [393 U.S. 503, 511] in Vietnam - was singled out for prohibition. Clearly, the prohibition of expression of one particular opinion, at least without evidence that it is necessary to avoid material and substantial interference with schoolwork or discipline, is not constitutionally permissible. >>
<<They caused discussion outside of the classrooms, but no interference with work and no disorder. In the circumstances, our Constitution does not permit officials of the State to deny their form of expression. >>>
…so it seems as though these school officials clearly stepped on their collective dicks, from a constitutional point of view.
While I’m sensitive to the feelings of minorities on the matter, my first adherance and loyalty is to the constitution of the U.S.
I think case law pretty clearly upholds the right of these kids to express support for the CBF.
