First Amendment rights on campus, speech codes, FIRE
Public colleges and universities are amongst the most frequent violators of First Amendment freedom of speech and press. Even though private universities are not covered by the First Amendment, they tout free speech, academic freedom etc., while many, at the same time disparage or punish it in certain cases. The do this usually via campus "speech codes." If you want an example, see this one from Framingham State University. FIRE is an organization that fights aggressively for student rights. It is non-partisan, but since most university speech codes lean sharply left, most of the students defended tend to be conservative and/or religious. Support FIRE!
