There is a continuing controversy at the University of Louisville, where representatives of the KKK claim free speech rights. (See also: here). Communications professor Ede Warner argues that the klansmen should be barred from speaking on the grounds that they are terrorists. Warner has a point, but it's been quite while since the kluxers were a serious threat in the United States. I'd argue for allowing them a forum because their own representations are the best evidence of their pitiful inanity. Seriously, folks, in the long run undergraduates are quite capable of recognizing nonsense when they hear it.
Update: Erin O'Connor's Critical Mass has more on the background to this story.
