Andi - don't you know, women that are good looking are not supposed to possess any intellect. You are just an adornment hanging on our arm! You can't have brains and good looks - it goes against nature! ;)
Seriously, I think that some men who have low self-esteem, lack confidence in themselves etc. are threatened by smart, self-assertive women. Also, the women stereotypes in the media - models, film stars (in the past)are portrayed as mostly airheads - you are only allowed to look pretty and not spout anything remotely intelligent. If you do, it is so out of the norm that some men cannot handle it. In some men's minds, woman are not supposed to be equal, and if they come across that way, its a huge threat. Sad.
On the other hand, there must be a lot of men like myself that find an intelligent woman incredibly sexy. If you can teach me things I don't know, your value goes up exponentially.
