YY, agree with that sera.
fib - oh, that is infuriating. 
I was talking to a friend of mine recently, and he was saying that gender identity is pretty much fixed in early childhood, and you simply can't socialize women to have the characteristics men have. So what are those, I asked. And he reeled off how boy toddlers are already more assertive, more active, more vocal, etc. etc., while girls are more emotionally mature.
After we'd argued back and forth for a while, he started getting fed up and claimed I wasn't being respectful of his points.
So I asked him if I was being emotionally immature and, to be fair to him, he totally got where I was going.
The upshot, though, is he agrees I'm an argumentative, aggressive, vocal woman but still believes gender identity is largely fixed. 
It just drives me bonkers, the way any exception to the argument is twisted to show that it's still really fine to discriminate against women.
