“What basic civil right did you mean, by the way if you meant free speech, no. The courts are wrong in saying that students have free speech rights in school. You cannot read such a right into the First Amendment, it is a pernicious invention that has helped destabilize the school systems.”
Schools do not have the priviliage of defining what is considered to be free speech.
The courts do.
And when a school oversteps their boundry with respect to controlling forms of free speech, the courts step in. Just as they did in Tinker v. Des Moines Independent Community School District, 393 U.S. 503 (1969).
