Yeah I agree that generally it makes a lot more sense to let it be published and then call it out for what it is afterwards. A university not giving someone a stage isn't censorship though... By giving someone like that Milo guy a stage a university (or school) would implicitly legitimise his thoughts to a large part of the population, and I'm not sure they academically warrant it. (At this stage I have to confess that I know preciously little about that guy and am not really inclined to dig deeper by what i've read up to now).
Let the idiots publish their pseudo-intellectual gibberish on their own platforms (don't censor it) but don't validate it either by creating a situation by which a third could say "well they both have their opinions". As Jay Z once said "Don't argue with a fool, a man from a distance won't know who is who". I guess the problem we're having world-wide is that we currently have an unusual high amount of eloquent idiots. Maybe we should roll back on those communication courses for all
But ultimately the idiots will always be undone by their own idiocy, it's just a matter of time and a question of how much damage they do in the meantime.
Yet to limit that damage we have to keep engaging with those vulnerable to their idiocy. I don't think there's a better setting for that than a thanksgiving dinner to be honest. Students need to be taught how to defend their values if they're to preserve them. They seemingly also need to be taught that it is ok if their racists uncle/grandpa/whatever doesn't like them for 5 minutes and shouldn't in any way change the picture they have of themselves. I think we agree that just shutting up can't be the answer.
I wasn't trying to put down US universities/colleges in general if that was how it came across. I'm aware that those mentioned in that article are just a couple out of a huge variation of universities, and each of those will have their own staff discussing their position on things like this. The overall trend (not just in the US) to avoid the (intellectually) uncomfortable is worrying though.
