Testosterone doesn't make men aggressive. Really.
If a man is behaving badly, it ain't testosterone, it's something else. The association between T and aggression is weaker (MUCH weaker) than other factors associated with aggression.
And, yes, this is a feminist issue -- because to imply that bodies with higher T have higher anti-social behavior is literally the definition of biological essentialism. It also implies men can't help it, which is also false.
