Unfortunately I've had to help quite a few men understand and fix their bias against women... Even worse. Almost always what gets them is using someone they care about. Okay. The threat of violence isn't a big deal. Would you let your mother walk alone at night? Tell your sister or daughter don't be scared to walk through that group of men, no need to find another way around? Would your mother have been terrible if she had worked instead of being a stay at home mum? If a man assaulted your family would you think they were making it up or blowing it out of proportion to get attention? So many things. Even in relationships I've had to ask "how would you feel if your step dad treated your mother the way you treat me? If your little sisters bf did what you just did?" It's not relevant to them half the time until it's someone they care about. Then it changes from women are liars and have privileges to "some women". Next comes asking how can they know for sure which women are some women? Where they present when the in incident happened? Can they say without a doubt she didn't face discrimination because she was a working mother vs a father?

It also helps to break it down for them. Single mothers are supposed to take care of their kids? So why vilify working mothers? They're just looking for child support. If you believe she should have to take care of that child because she made it, "spread her legs knowing what could happen", why is it different for the man that got between them knowing what could happen?

Or a personal favorite 🙄, make them see how it harms men as well and they are normally more open to it.
