I am no fan of Charles Murray or his work. I suspect that if I read it exhaustively, I would find much to criticize. I have read The Bell Curve, and I'm unconvinced by his arguments.
That said: this behavior reported here by a group of Middlebury students is appalling. If free speech on a campus means anything, it means that people who are invited by members of the community - people who apparently thought he had something worth listening to - be allowed to share their views with decorum and civility. Shouting a speaker down, and then jumping on his car as he attempts to leave, are inconsistent with this notion.
The open letter referred to in the article linked above tries to square this circle by arguing, essentially, that there are certain views that are outside the boundaries of free speech protection and which therefore can and should be censured. It also argues that the airing of those views in and of itself constitutes a threat to other members of the community, a form of (their word) intimidation.
This is precisely the kind of division I spoke of in my most recent blog post. It will not get better by shouting and pounding on cars, or even by the more civilized means of "de-inviting" speakers. It will only get better through real dialogue. Whether a public lecture is the best form of that dialogue is another question, but I suspect that the students protesting made no real attempt to have an open conversation with their fellow students who had invited Murray in the first place.
I also suspect that the students who invited Murray in the first place knew darned well what they were doing, and that some of them are likely quite pleased to have provoked their liberal brethren into an overreaction. This is combative politics that divides. Rather than invite a controversial speaker to demonstrate your power, why not have a direct dialogue between student groups?
The students in question (on both sides) probably don't see it this way, but this is a politics of force. It is a politics that says, I am right and you are wrong and I am going to use all of the power at my disposal to impose my will on you. It is as anti-democratic as anything they are protesting against. I do not envy my colleagues in the Middlebury administration as they try to untangle this mess.
