The issue, of course, is to define hate speech. Most speakers being "no-platformed" on American campuses these days absolutely do not "encourage violence towards specific groups of people". It seems sufficient that they challenge prevailing viewpoints to be shouted down. There's this totalitarian attempt at labelling any disagreement as "micro-aggressive", to equate it to hate speech that must be suppressed. But none of that remotely reaches the threshold for legally defined hate speech in most countries. It's even usually completely orthogonal to that scale.
