I didn't watch the documentary, but I just watched a 4 minute clip from him being on Letterman, and to me it reinforced the stuff the author was talking about from the link Thinker provided.

Maybe he is going through a bravado phase. When Letterman asked him if his interactions with women were different he said, well I think I frustrate my girlfriend more. I can be an "A." I can be insensitive. I can be a guy.
WTF?
