Fair question, and if anything gets opened it will be my fault lol.
I don't mean if your wife looks at you the wrong way, or cheats on you, or yells at you, or anything like that.
Think of the reasons we aren't supposed to hit women - because they are inherently weaker, more vulnerable, and hitting somebody who can't defend themselves is cowardly. Same reason you shouldn't hit a kid or a puppy or a cripple. It's not because women are somehow above being hit.
What if a woman is bigger than you, stronger than you, and you are the one in a vulnerable position? I have no problem with a man who defends himself against a tirading woman operating under the assumption that she is untouchable.
Everybody has the right to defend themselves from anyone else. If a woman attacks me on the subway I will stop her in any way necessary. In most cases it would only take grabbing and holding her or something along those lines, but if that doesn't work a good chop to the neck should do it.
