>>A public university is private property? Who does it belong to?<<
Unfortunately it isn’t that cut and dried. The administrators of a facility can still set rules of conduct. The example I gave of not allowing political posters, buttons and the like is just one example.
Just as employees can choose to work elsewhere, students can choose to attend another university.
You as a private citizen cannot just walk into a state university campus without a legitimate reason.
This is far from a slam dunk but I think there is probably some meat on the bones in favor of the students.
I have walked onto the campus of several universities and no one ever asked me what I was doing there.
And remember, the people passing out copies of the Constitution were students at the university, giving them a “right” to be on campus.
I’m pretty sure the university loses on this.
