Is it alright with you that professors set up classes to ridicule other people's belief's and then call it a chance to give them a slap in the "big fat face?" Why the silence over this a$$hole's actions? Do you sense any kind of cause and effect present between his actions and the consequences? If you set up a class like that would you expect accolades?
Your blindness in this case likely extends to other blindnesses.
Speaking only for myself, Mirecki was an ass. He did apologize, but even if he hadn't, it still doesn't deserve violence in response.
