Of course on principle this is a disgusting form a censorship that could come to bite them on the ass if it continues to be culturally accepted. They seem to forget that things like interracial marriage, or people of color even being allowed onto these schools were once unpopular ideas.
If they continue to create a culture of violence and intimidation against anyone who dares utter unpopular ideas in their vicinity they'll snuff out any hope of future social revolutions from happening. But this seems to be what they want. It's in some ways an ultra-orthodox, conservative, perversion of left wing ideals.
Does student censorship affect that directly? Probably not, but students running the school more than teachers certainly could.
