Sorry but I am female and I totally disagree - ANY form of abuse or violence whether it be physical or verbal should not be tolerated regardless of what sex the person is.
Of course.
But a man hitting a woman is worse than a man hitting a man. Why? Because men are physically superior to women in the strength department. It's just a moral law. And fair enough if you, as a woman, disagree. But men should share this opinion more than women. All men know hitting women is totally unacceptable, but as I outlined before, there are circumstances where I believe hitting men is okay! Eg. If a guy was forcefully coming on to my girlfriend, didn't respond to a verbal dissuasion, then I would deem it fine for me to put him on his arse. If a woman was doing the same to my girlfriend o), it would not be okay to do the same.
