Much like you cant be forced to do something you dont want to do by a paying customer in the US (look at the Colorado cake issue) the same applies. Even the protests in public universities they have laws to follow.

By far the largest customer for these schools is the Federal Government. Look at the billions spent on research.

Your first amendment doesnt protect from hate speech and other illegal things that occurred. Schools completely failed to address the illegal elements that were within the protests and the ruined them because protesters then covered/hid people who assaulted or committed other crimes.

Your idea of the customers is fundamentally wrong because the biggest customer if you want to measure that way is the Federal government. Your first amendment doesnt protect you from other crimes in the name of free speech. Now if the protesters had turned over those who committed the crimes that would have been one thing but they refused and thus the whole thing became a security issue and was shut down.

I have a right to bear arms but that doesnt mean I have a right to shoot someone. You have the right to say what you want but when you cross the clearly established Supreme Court approved line that it is no longer free speech well there are consequences for your actions and to think you can live consequence free is a pretty wild take.
