If I had a son I would teach him to wrestle and I'd make sure he got good at it. Because in any combative situation, unless one's opponent gets an effectively sneaky or lucky punch in a wrestler will always win the fight. And knowing a few very basic wrestling holds makes it absolutely unnecessary for a man to ever strike a woman.
Even in the case of an aggressive drunk or a woman who is persistently violent it is very easy to induce extreme pain without causing her any real harm or damage.
I think it's obvious that if you're in fear of injury or for your life, and you can't get away from an insane woman who is intent on putting a hurt on you, you are justified in doing what you have to do to survive.
But these guys are talking about breaking a woman's nose for blowing smoke in a bar, about beating the shit out of a woman, who is standing behind a man, because she's calling names. They're philosophizing about verbal VIOLENCE, a term they have made up, and how it can justify physical violence as a reaction to it.
The thread was created by a freak, and it attracted every over the top woman hater on this site (except Paulie, who is oddly silent which means he's probably in jail right now) who commenced to discuss all the situations they can think of where it can be okay to beat on a woman.
It's not a discussion about whether or not it's okay to smack women around. It's a justification thread for hitting women, and a venue for men to encourage each other in their abuse, real or anticipated, of women.
