What you mean is shame on the university for allowing censorship, MMTU. Jack is right. An open society has to allow open debate. I can think of very little more philosophically disgusting than this professor standing in front of a group of students on the USF campus and soliciting funds to support terrorists and the "good" work they are doing. But, you of all people know the danger of censorship because you've been its victim.
OTOH, as soon as these folks step over the legal line in a conspiracy, throw their butts in jail and lose the key!
