Hit back. Or so I used to think.
Then I discovered the legal system offers women a special designation that automatically gives them the right to assault people bigger than them, particularly if they're male. That simply retaliating is not allowed, even in self defense. Moreover, since women rarely fight their own battles, you'll have to deal with their boyfriend/husband/father and male friends, who'll hunt you down if they don't jump you the moment the fight happens.
The system's not fair. So you can't play fair either. If a woman mouths off, you walk away. If she hits you, you call the police. It's gay, but it's the only way to protect yourself as a man. Otherwise the deck is stacked against you, and you will go to jail.
A girl hit me in the face in high school one day under similar circumstances as the video. I punched her back and she passed out. 5 guys dropped their books and jumped me.
She got a 3 day leave, I got expelled and it fucked up my academic career for a year. That's how it works in non-Muslim countries. Over there, they keep their women on a leash, and if she mouths off, they're allowed to set them on fire. Here, women hold all the keys, and control all the doors. That's a sad reality. It's why men can't be men anymore.
