You see it all over youtube, a girl is hitting a guy, people watch, people stare, some even cheer her on.

Then he hits back.

He might smash her teeth in, he might just push her over, he might even struggle against a woman of near equal strength.

And yet out of the blue, people flip their shit, usually other men, who tackle/beat up the VICTIM of the assault.

Does the existence of these people, who punish men for defending themselves, promote female on male violence?
