I think we as common human often make the error of putting someone on pedestal, even when that person has some flaws (whatever they are). And the fact is that great men and women alike, often had or have some negative factor about them. Nikola Tesla in his youth thought that women are superior to men and was quite fond of them, only to revisit that view in his later years, by 180 degrees, thinking that women's biggest fault is trying to imitate men (I don't find this sexist btw, and his take can be seen as plight for femininity). And many people simply do not care about it. Churchill, leader he was, if I mention in a crowded street "Churchill sucks!", people would throw bricks at me. Probably same would be with Margaret Thatcher. In art, it's similar. Someone might say "who cares about JKR views, I love her books". Which is to say, we all draw our lines. And vice versa. For e.x, I love Howard Chaykin, even though we would probably disagree on a lot of things.
