I've never hit a woman, but that doesn't mean that I will never hit a woman. And I seriously do not accept the "woman & man thingy", If you accept to hit a man, then it's ridiculous if you refuse to hit a woman (if she / he deserves it). It's overall hitting a human.
If a woman punches you why wouldn't you punch her back? If a woman swore at you, you would naturally swear back so why not do the same but in physical terms...? If a woman started a fight with me I would consider her as a human and retaliate
