Only exception is if the woman comes at you with a knife or gun. All bets are off then, as you are never required to gamble your life.
Just wondering what your situation in life would be for that to happen? I've had a knife pulled on me once in my life, by a guy, and lived to tell about it.
I can only imagine the male would have to do something heinous to provoke the woman, or she is bat **** crazy, and in that case why aren't you running away from that as fast as you can?
