He's also been the victim of some pretty vile smear campaigns and is still going on. I know if I was the target of the crap he got, I wouldn't want to continue doing anything anymore.
I guess that's why fake, phony, status-oriented people can't stop themselves criticizing him for all his superficial shortcomings. It's as if his genuineness is a trigger for them and they need to attack him to feel better about how phony they are in comparison.
