I think with a forced gender binary, any advantages are double sided: men are respected, but not allowed to show emotion; women are cared for, but infantilized; men earn more money, but can’t ask for help; women are trusted with children, but not computers; men get to go on adventures, but can’t back down from a fight.
Like, with other forms of bigotry, there’s a much clearer “winner,” but sexism fucks everyone. I don’t think it fucks everyone equally, but it does negatively impact everyone.
I could see children deciding that this is how they get gun control laws.
