What you've got to understand about this is that it's a self-fulfilling prophecy. We tell boys "oh you can't help being violent, it's just in your nature", and then they go out and do violence, and we say "well this just proves it".
It's a core part of what we call the "boys will be boys" phenomenon, where we forgive any manner of misbehaviour from boys and men, and shift the responsibility onto women and girls. We blame what a girl was wearing, or the fact that women keep refusing to go out with some dude. Or we blame mothers. It never seems to land on the guys themselves. 2/
