The guy at Drexel certainly had the right to say the things he said. But he was also an embarrassment to the university. Genocide is not a suitable subject for humor. There was also his nausea over hearing that someone had given a soldier a first-class seat on an airplane. The professor is no one I would want to have teaching any of my kids. Which is not to say Drexel couldn’t have handled it better. It is, after all, important to defend speech one doesn’t approve of.
