How do you deal with sexist wankers?

Especially, if you’re related to them. Is physical violence ok? Seriously, whiskey-tango-foxtrot, how do you deal with a person who treats women as their property? Or a second class citizen?

My step-brother is an asshole, do I punch him in the mouth? Or what? He’s been taught that women are worthless kitchen slaves, and he’s not masculine unless he’s an ultimate bastard.
