Pretty much, yes. The US system is fairly ridiculous so a lot is left up to judges and common law - e.g. whether rights can be stripped due to being convicted or a crime or oer a judge's order. But freedom of speech and assembly in college campuses, especially by students, fits squarely in what is normally protected. Hell, outside right wing groups regularly try to hold rallies in a camlus near me. Cops never go after them, let alone judges.
