I assume this is regarding propaganda / courses from the college themselves. You can't "end" people speaking or even violence because the colleges can't know or be held accountable for what a student is going to do in advance.
What happened to free speech in America? This is what ya”ll voted for. If we allow him to curb speech on college campuses, what’s next? Can’t talk about who knows what and get jailed for it?
Free speech must be protected regardless of who is saying it. So much for America First. #America #Trump https://video.nostr.build/3e4df7d86d3c5ae8c2f7ecd7b283fe11b5340ed8b76a197a8d6105cf9dcdaeff.mp4

Also there may be action to ban or prevent college funding/ accreditation to certain groups such as:

You might be surprised what kind of weird stuff passes for courses in some colleges
