Why not just expel any and all students who committed or threatened violence? With maybe a restraining order to stay off campus.
The complaint isn't about any personal threats of violence, from any specific protestors, though there might have been a few of those.
The complaint is more broadly about the protests' anti-Israeli rhetoric, which create a "hostile environment" that makes some Jewish students feel unsafe.
In April, the student filed a lawsuit saying her education had been disrupted by a hostile environment on campus when anti-Israel protesters put up encampments on Columbia’s lawns.
No problem if the anti-white rhetoric in classrooms -- or DEI sessions -- makes white students "feel unsafe."
