I used to like him because I thought he seemed genuine, had interesting ideas, and was very open about his own struggles.

But as time went on I started to realize that he had a very rigid worldview and all of his talking points and meanderings were just like watching mental gymnastics. He would take many different puzzle pieces and force them to fit together whether they actually did or not, and then turn his rage on anyone who didn't see things the way that he saw them.

He has a very high opinion of himself and his capabilities, to the point where it's almost impossible to get through to him and get him to consider a different point of view. Getting older, I realize that pseudo-intellectualism is probably some kind a defense mechanism or coping strategy for him. It's not uncommon for people to use rationalizations to protect their own ego.
