I too enjoy Prof's posts. His discourse is cerebral and pointedly, unabashedly down the fence, if people take the time to read understand what has been written. I do not see any insults in the posts that require such vehement, even venomous responses.
Everyone has a right to express his/her opinions, but this is not the forum for nastiness. I have had my share for expressing my opinion, and I'd probably expect more from certain quarters.
