I would have pushed her away from me, but I would never hit her.

Were I live by law if a girl hits you 3 times you can legally hit her back, but I still wouldn't do it cause its wrong in my eyes

The way I see things is it doesn't matter what gender a person is if they aggressively hit me in any way I will hit back, I don't believe in the old ways of not hitting a girl, I believe in self defence. I mean who cares about what others think if I feel threatened I will strike back.

It is a sad thing in society for how women are always victimized compared to men. Like the example you stated about it being funny for a man to be hit by a woman, if a man touches a woman's private part(s) it is considered a form of rape, molesting, or something of that sort while if a woman touches a man's junk it is considered differently. This lack of equality of how gender decides if an action is good or bad is just a horrible thing in society in my opinion.
