You are totally missing the point, though. The problem is the ingrained stereotypes in society. Monkeys don't prefer anything, seriously. That was one test on *human* babies and it was so controversial it got shot down pretty fast. Monkeys and babies don't even have a concept of "trucks" and "dolls" to prefer one or the other. Gender Dysphoria can only ever exist in a society with gender stereotypes. Yes, I am saying that Gender Dysphoria is caused by society. That one guy who was raised as a girl? He didn't feel comfortable in a female stereotype and that is a form of gender confusion. Though not from his side, but from the side of society. You are shifting the blame here, the problem isn't people who don't conform to societal expectations, but those societal expectations themselves.
There are "proven differences", but not the ones you think. It has nothing to do with women preferring pink and the Sims, and men preferring blue and Gears of War. Neurodevelopmental disorders like autism and the like have NOTHING to do with this. Have you heard of a "Strawman" and "False analogy"? Yeah, that.
