Sexual dimorphism.
www.youtube.com/watch?v=O-Fpol… beings have natural biological differences between the sexes. We have different hormones in our brains which leads to tendencies in our behavior. Most men will naturally have a preference for one kind of thing while most women will have a different preference. There will always be exceptions, but that doesn't change the general rule of the tendencies. Pretending that biology is a social construct that you can just overcome with a little shaming isn't a good idea and, yes, will lead to even more problems down the road. You have your idea of how your idea will work, but this article demonstrates how it looks in practice.
Take for example another idea on race relations. The left seems to think that the best way to help the races get along is to focus exclusively on race and demonize people. That has lead to elementary schools bringing back segregation and teaching children to love or hate themselves because of their skin color

Do it right? Why do we need to force people to act a certain way at all? What's wrong with letting people be themselves and not freaking out and screaming about my soggy knees just because the boy likes sports and the girl likes barbies? Because that's what this article supports, abusing children for the purpose of supporting the ideology that human sex is a social construct.
You know there's a trend around the world where more developed nations, those where people have greater freedom to do as they like, tend to follow sex roles more strongly than in less developed nations where there isn't as much choice. This stuff is ingrained into our humanity. Is this evil? Are women who are happy staying home with the kids more oppressed than those who feel obligated to work jobs they hate? According to feminists, yes. The only way you're getting rid of it is through torture or extensive genetic engineering. Would you actually trust the state to have that power and not abuse it?
