Why do some people always defend the abusive woman when the man hits back with full force?

I had to do it when she kept hitting me in the eyes, and broke my glasses. The cops were on my side.

But I see arguments saying restraint should have been a factor, or proportional hits.

That's bullshit. Restraint could lead to biting and someone screaming until the cops come, and proportional hits won't stop someone.

If someone hits first, they should be stopped with full force, and the victim run away after.

I'm tired of this bias. And I'm tired of people painting male victims who DO HIT BACK as wanting to hit women.

Don't want to be hit? Don't hit first.
