@pony: It's not obvious.
First, I'm not so sure that "very few" women are involved in science. You can have a look here or here (external links). It's true that women are under-represented (a fancy way of saying less than half I suppose), but there're still quite a lot of women in science. Do you have any reason to think those statistics are fake/mistaken?
Second, if you give Roger Federer a table-tennis racket and make him play proper tennis against me (I'm mediocre) with a tennis racket, I don't think he can even play, let alone win. I'm even less sure that you can conclude I am the better tennis player. If societies restrict women's access to higher education (which many still do), then, isn't it obvious that women in those societies don't show up at jobs requiring higher education through no fault of theirs?
Third, why are you inclined to believe most women are unintelligent? Would you rather not listen to what a woman has to say because, well, she's just too likely to be unintelligent? Why not listen first, then make the judgement on each individual without passing a single judgement on the whole group?
Say, today you meet a woman. Normally you'd walk away. Today you're feeling weird and decides to listen. She turns out to be, say, quite smart: she knows how to light up a conversation, or dim it down if she so chooses. You wouldn't have know any of those awesomeness if you walked away based on a pre-conceived notion that women are unintelligent and not worth listening to. So, why keep that notion, that prejudice in your mind at all?
Last, I agree with you on one thing, aggression only makes things worse.
