Today, society teaches little kids that men and women are exactly the same: that they can do everything their counterpart does (edit: in Western societies). It's full of , but it's what feminists teach the youth. Therefore, if a woman is dumb enough to think she really can take on a man and hits him, he should have the right to defend himself. I'm not advocating that the man just wail on her, but one good hit would likely evaporate the situation.
