I was into legos and mechanos. Some family members insisted in giving me dolls. And they ignored the lists I made for my birthday or christmas to give me whatever they decided it was "more appropriate". When that happened, my mother told me to play with the dolls, to show that "I appreciated the gift" whenever those relatives visited. So from their relatives perspective "I liked" dolls. Even if I found them boring as hell. They would have say the same than you about "biology", yet they systematically ignored my preferences. Or the ones from a cousin, that likes dresses, but since he was a boy, they were, so worried that he become "gay".

So there you have it, little children forced to lie to relatives so they didn't feel bad about their sexism. We weren't allowed to show our disappointment. Or our real interest while those relatives were present. Because we would have been seen as "ungrateful".

So indeed there is socialization to little children. There are ven sociological experiments where people treat differently the same baby depending on the sex they are told the baby is.

You claim there is no socialization to babies? They are socialized from the moment people start speaking to them. From the second that they start giving you presents depending on the sex. Even before they born, they have already classified them. They buy pink things for girls even before they born. And some people refuse to reuse old pink clothes in boys. those are adults projecting in children.

And let me tell you, I ended selling the dolls the moment I was allowed to do what I wanted with them. They did fetch a good price, since they were new because I didn't played with them as a child. I bought comics with the money which apparently was really offensive to those relatives because, why wouldn't I want to keep those toys that I did liked so much when I was little? It must have been feminist getting ideas in me. At no point they considered they were wrong from the beginning and that they were the ones at fault.

Because that is the gist of it, some people want women to perform their forced idea of femininity even if that make us unhappy. They need us to do the caring, the domestic chores and all the while pretend that they aren't being unfair by denying other things that we want. So the "biological differences" are their go to excuse.

But the fact is that many things deemed feminine like makeup, heels and wigs? Well, Louis XVI. Men used all those things. And it wasn't just about clothes, take K-pop, they are considered "feminine", yet, girls love them and find them masculine. And if you look around through history and countries, what is considered feminine and masculine changes. It is arbitrary. And attempt to fit us into little boxes and that also restricts boys potential.

But you are right, it is in us to stop pandering to those ideas. So that is what we have done. Yet, the same people that used to give money to our brothers while give us frying pans to us (this is literal) complains how we are "destroying families".

If you have had to put up with being treated worse all your life, you would be angry. But many of us aren't angry, the ones who are angry are the ones who would like us to perform for them. They project their feelings on us and resent that we are not what they want us to be.

So yes, our potential is wasted because others want us to be their carers. And they are so blind that they didn't even realize that they are doing that.

Look around you, how many times have you hear an adult telling a boy that "something is for girls"? Or a girl to not run because it is not feminine and she would "show everything" since she is wearing a skirt? You can even create a thread with all the comments we have heard as children to set us in the gender-approved way. And it was constant, not just by families, but even by extrangers that felt the need to lecture us. Go ahead, go to a park where little children play and record a video. Pay attention to what people say to girls and what they say to boys. They treated them different. Even to babies.
