Nancy, now you're just shifting the goalposts!
In your initial reply, you said "no guy should slap a lady" STRONGLY insinuating that the guy in the vid was wrong to hit the lady. When pushed to a corner, you then claimed that you were not talking about the guy in the vid, even though your comments were clearly related to the video and my subsequent comments regarding it !

The guy wacks her back and then keeps ranting about "why she slap, why she slap"?! What a freak!
No guy should ever hit a lady

Quoting you above; it's clear that you're speaking about the guy in the vid after which you said "no guy should ever hit a lady"?? Don't try and split hairs with me young lady, cos its obvious that you were applying that "no hitting a lady" argument on the guy in the vid, when we had all quite safely agreed that it was not his fault!
And yes, "an eye for an eye" does work. if the guy was rude to her, then she should be rude back to him - NOT exceed him by attacking him physically (which is what you are proposing).
And whats the difference between a girl hitting a guy because SHE THINKS she is right to hit him, and a guy who slaps her back because he THINK he is right to do so? Very little! In fact, one could argue that at least he didn't hit her first.
