Would you silence a dissenting view?
I would not. I would let them to speak in public so that everyone can see what idiots they are, and sieze the opportunity to mercilessly ridicule them.
I am reminded of a similar situation several years back when the Smith College Republicans invited Ann Coulter to spout her particular brand of idiocy on campus. "Coincidently", that night Tristan Taormino was also invited on campus to discuss her book The Ultimate Guide to Anal Sex for Women. There's something unmistakably brilliant, almost poetic, about that particular juxtaposition.
I implore the students at MSU to not miss this wonderful opportunity for levity.
