The nature argument doesn't say you can't change it. Just that the source of your inclination is built in genetically and from birth rather than being a result

The nature argument doesn't say you can't change it. Just that the source of your inclination is built in genetically and from birth rather than being a result of nurture. Are boys more aggressive due to nature? Considering that we know what testosterone does to behavior and the stereotype exists across most cultures and all of history, I don't think "boys will be boys" means they were nurtured to be that way, at least not to most people.
