Nichi, the point is that they are hypocrites who have no problem silencing voices they are opposed to while allowing those they approve of to do and say what they want.
"There are several underlying causes for the discomfort of the college presidents, not all of which have clear solutions. College campuses have been inundated with pro-Palestinian activism, which sometimes contains a threatening tone to Jewish students. Campuses have also been struggling for a decade or so with left-wing demands to make campuses “safe,” which has entailed cracking down on criticism of the political left.
So what does it mean to make Jewish students feel safe on campus? One way would be to crack down on anti-Israel rhetoric that might make many Jews feel threatened. That would be consistent with the methods universities have sometimes employed to protect other minority groups. But it would also be deeply illiberal."
A more limited and defensible response would be to police conduct. When mobs of students disrupt classes and make it hard for students to walk around campus without being screamed at (or shoved), that creates an intimidating atmosphere." -- ibid
