What's weird is that nobody really disputes this. Feminists think boys are little monsters, and so do conservatives. The only dispute is why and what to do about it. The why is actually settled science. But wait that sounds derogatory.
Boys are more hyper, more competitive, more aggressive, more violent.
These characteristics are hardwired. That's what we do, I'm sorry. If you want a grim example of the stubbornness of human nature, consider the example of Bruce Reimer, as told in the horrifyingly compelling book, As Nature Made Him , by John Colapinto. A doctor at Johns Hopkins named John Money elatedly persuaded Reimer's parents to let him turn the boy into a girl. Money was a dedicated gender theorist beloved by feminists for his insistence that all gender norms are socially imposed.
