I'd NEVER use physical force on a man OR a woman except in self-defense. If I did, I would fully expect to be hit back. Gender excuses nothing. I'm amazed at the voting -- that more think being a woman excuses them. It doesn't, you lil' rabble-rousers.
If I were attacked or threatened with attack, I would most certainly try to defend myself with some fairly effective dirty street fighting I learned in Tai Kwon Do. But even at that, with a man, it's a fight I'd fully expect to lose.
Any guy who physically assaults a woman, and, btw, that includes folding your arms in front of you and pushing her around the room, grabbing her forcibly by the arm, or anything else physical, is a 100% Grade A Genuine ***hole. Any woman who does the same earns the same label.
