Thank you for sharing the male point of view. It is human nature to defend yourself, but the rules are wrongly changed when it's female-on-male violence and the big part of why that is is what you stated: the culture of chivalry at ALL costs (which isn't right or fair). I was raised to keep your hands to yourself, to treat people the way I want to be treated and that includes the opposite sex. I never thought it was cute to slap, punch, assault a man, either and I never thought a man didn't have the right to defend himself! That tide may be changing, though. Men aren't taking it anymore; they're not walking away and they're not letting a woman go off on them and abuse them. Jermaine calling the cops on Halima is an example of that. He could have easily smacked the living hell out of her and never called the cops. Apparently there was enough there to arrest her and charge her with a domestic violence charge and not HIM.
Whoopi spoke about the subject (female on male violence) on The View awhile back and summed up beautifully that women need to stop thinking men won't hit back if we hit them. Keep your hands to yourself, unless it's in self defense is my motto.
