This document discusses the history and application of free speech rights on college campuses under the First Amendment. It outlines landmark Supreme Court cases like Tinker v. Des Moines that established students' right to symbolic speech of protest in schools. More recent cases like Gerlich v. Leath ruled that universities cannot ban controversial messages like advocating marijuana legalization. While schools aim to avoid disruption, courts have sided with students that silent, symbolic forms of expression are protected under free speech. There remains debate around where to draw the line between offensive versus censored expression on campus.
