LOL! Now why bird flu is relevant, I don't know, but...it landed on my funny bone!
The other truth is, that men are taught to never hit a woman. And that is a good thing. And most guys know that they should never resort to hitting another man. On occasion, though, that may become necessary for self-defense, and if you are hit first by another man, then all that is out the door.
However, as cripplecreek wisely noted, there is a double-standard here. Even if a man is assaulted FIRST, they will still most likely be the one sitting in the stripey hole, in some cases, even if they DO NOTHING AT ALL. When the police come to the scene of a domestic disturbance, they have pressure on them to walk away with someone. And, it AIN'T gonna be her.
Actually I've seen a few episodes of COPS where the woman got carted away. Of course, that is the exception to the rule.
All I can say is that men should be very careful who they marry. If, during the courtship, the woman shows any signs whatsoever of being vindictive, hateful, etc., get away and stay away. For they will haunt your life forever once you let them into it.
