it depends if it was a state university or not. and what the class is. In a class on religion, it'd be on par. If it was a course on metallurgy, well he'd be a bit out of line. Not worth suspension, but still. there are situations where abuse of authority is of concern.
The inherent message of the story is what I take the strongest offense to. Professors are morally currupt eggheads who don't deserve respect and wish to oppress the god fearing public.
There seem to be more instances of fundementalist religious teaching encrouching on students to the point of exclusion and ridicule(see story on teacher forcing muslim girl out of class for not being christian) that makes me find these types of stereotypical stories a little annoying.
