Do you think that men who are intelligent, strong in personality and outgoing, and a little sarcastic, a little funny, appear to people as more charming and praiseworthy than a woman who has those same characterstics?
In my own experience people are more likely to dislike a woman who is that way, calling her obnoxious or controlling or just unlikable. Even annoying. For some reason the woman seems more threatening. I just can't figure out why. Not to say that no one likes that kind of person, it just seems like more people actually go out of their way to dislike a woman like that.
I'm not saying this only applies to famous people. It seems to apply even more to just normal people, because famous people usually at least have looks to contribute to the "like" factor.
