Here we are in the same old cycle. I say something that should be totally unremarkable, and then some people are perfectly mortified that I'm not buying into the same post-modern notions they go for.
To encapsulate my viewpoint common sense, if my wife were to come home and find that I was looking up naked porn ladies on the internets, and if she were to give me a black eye, I would consider it well-deserved. I would not report it as an assault. No, I'm not saying it should be perfectly legal, but I would expect the police to be laughing at me while they took down my statement.
(For the record, my wife has never been violent toward me, or anyone else that I know of.)
Am I saying that it is OK for women to hit men just because they are angry? No.
Am I saying that men who are severely, or regularly beaten by their wives should shut up and take it? No, I'm not talking about that. The woman in the story apparently was not able to do that much damage. Those are the kinds of "assaults" I'm talking about.
Am I saying it would be acceptable for a man to hit his wife for the same reasons? No. Hitting women is only acceptable for circumstances like self-defense, obviously.
