No, look. It's very simple. ALL violence against human beings is unacceptable, regardless of any aspect of the perpetrator or victim. End of story. If you start with "men hitting women is wrong" you very soon get to "its not abuse when a woman hits a man" and those are VERY dangerous lines to think along. There is no need to point out specific types of cases based on any attributes of perpetrator and victim - its ALL wrong. Even in retaliation. Or revenge.
