Just imagine the headlines if they did do something more impactful like taking a stance and expelling the relevant students. Many headlines would be conflating this expulsion with racism and who knows what other rhetoric. Not only that, but the university would be sued for years if they did this. Also, this guy would get fired in at-most a year. Not necessarily for his stance, but for rocking the boat and bringing so much attention to the university.

People don't realize just how much the rules are stacked in favor of bullies.
