Bitter?
Yeah, some of his diatribes are vicious.
I wonder if anyone actually LIVES with him; he must be a mess.
Fifty years of tormented drug use gave him his perspective.
He was a problem child as a young adult and even worse after he joined the Airforce. Always looking for something to bump him out of reality. Probably too bright and not directed properly when he was younger.
His pretty scary bio is <here.> Still gotta love the guy for his "perspective".
