2 common threads about them. The first is that they rarely discuss specifics about what positions or what opinions got them censured. The second is that the comments section is typically full of drive by commenters who aren't responding to the content of the post in particular but to the idea that a professor might be censured for [their view].
I think its fair to say that everyone believes that universities ought to be places where it's possible to explore radical ideas. But sometimes, things are just wrong. If a professor teaches a load of students that the Sun orbits the earth, they're going to be censured, and nobody would be surprised.
I can't say anything to respond to this particular post, because I have no idea what this guy in particular is even being censured for -- whether the idea itself has value enough to discuss. The fact that some students believe so is certainly not a high enough standard.
