Girls, when is a kick in the balls fair?
Do you think it's fair to kick guys in these situations? Would you do it yourself?

1. You and him are verbally fighting.
2. He calls you fat.
3. He calls you an insult like b*tch or sl*t.
4. He makes a misogynistic joke.
5. You're going to fight him.
6. You're fighting him AND he's winning.
7. He cheats on you.
8. He (not your SO) touches your bum/tit (and then withdraws).
9. He physically attacks you (outside an agreed fight).
10. He's trying to rape/raping you.
Or in any other situation?
