Right, a child should accept responsibility for what exactly? Being born male?

You can make a choice to not commit crime. Or not kill people.

I'm not denying that they are responsible for their adult actions, but it's clear that the abuse they are given by their mothers isn't helping.

You're pretty heavily going "but it's not their fault, they were fucked from the start". I've seen people get out of shitholes and bad situations. Just takes work.
