Just a note on the idea that teaching girls to choose or be safe is an answer...
Male violence is a perfect self-perpetuating system. Men beat and rape women, who then have children. Those children witness violence and/or are victims. They either stay in the home, worse and worse. Or go into care, still worse. They act out, self medicate, have sexualised behaviour. Then some predator picks them up. Hands them around. They then have a child...
I can teach my DD to be slightly safer. But that just transfers the violence to her mate. Whose mum threw her out and now she's living on sofas. Who tells her to choose wisely.
It has to be men changing or being locked up to protect us.
