I occasionally try to think of ways to convince people that misogyny is an actual cultural thing without having to argue about statistics and sources.
And I think I found it:
"Bitch" is an insult to a guy because it implies that he takes shit from people, and to a girl because it implies that she doesn’t.
I usually talk about what people think of when they picture an engineer, soldier, doctor, etc. in their head. This seems way easier, though.
