I'm not really sure I get this. I mean, if someone has indellible flaws, I don't think it's right for that to make anyone less of a fan of their work... because, after all, being a fan of someone's is about being a fan of what they do, not what their personality is like, in theory. Obviously maybe you'd think less of them, but it shouldn't change your perception of their work.
That said,
Take It Like a Man is what George wrote. He had every right to make it as cynical, bitchy, or whatever as he wanted to. He has every right to say what he wants to about people in his life; if it didn't portray his true personality, then what sort of autobiography would that be? A dishonest one, that's all about making things appear pretty, when they don't particularly sound like they are. And you just said that dishonesty was a bad thing, didn't you?
I'm not trying to start an argument, but just think about what you say before you say it.
