It was here at the University of Pennsylvania last year that a white freshman was charged with racial harassment for calling a group of black women 'water buffalo.' " It was also here, Mr. Buckley reminds us, that a group of students stole and destroyed copies of a student newspaper that carried an op-ed piece they disagreed with.

Mr. Green starts by welcoming "any debate which forces conservative Republicans to become ACLUers in defense of the First Amendment."
