How far do you go? At what point do you stop? Or do you not? A lot of violent people like to use the protection of a third party as an excuse. Violence only works as a control mechanism because of fear. There's a huge difference between defusing a situation, restraining an aggressor (until they can be removed to where they are no danger to anyone) and becoming an aggressor yourself. And that last one just reinforces the mindset that violence is an acceptable control technique. Also: Why single out women attacking men as a fair point? what about women on children? children on children? pensioners on men with learning difficulties? teenagers of mixed african, welsh and english descent in wheelchairs on otters? It's all bad in the end really.
