It's also (often) not internally consistent. If you've got a sword & sorcery story where everyone has some sort of power, it doesn't make a whole lot of sense for your female characters to be vulnerable damsels.

I know ASOIAF isn't really the best example as a whole, but the bits with the free folk beyond the wall hit the contradiction pretty well, since the women are warriors as well. There's a bit from Tormund, I think, saying that someone "can own a knife or a woman but not both." And fantasy forgets that all the time. Your characters have fucking superpowers, dude. An armed society might not always be a polite society, but the "impolite" people are gonna be short lived.
