That's most of my issue with him. If he's not an over the top, confrontational guy in the real world, then don't pretend to be one in the media. It's the very reason that I think most reality TV is anything but, and generally an insult to one's intelligence.
And if he really does have the personality that he displays, then he's a disrespectful asshole. Either way that persona does him no good in my mind. I feel only contempt for him.
The bigger picture is that we're telling people that being kind and being reasonable is a loosing way of life. Reality TV has caused immense damage in that respect IMO.
