This may indeed be true. A woman slapping a man's face is "initiating" the occurence. But, in the same way a man is 75% more likely to succeed in suicide, a man is also much more likely to cause significant harm in a physical altercation. This is my opinion, but given human behavior, I would suspect it is true.
I don't take it personally that you called me ignorant, even though I would not use that word with someone I don't know.
I do, however know men and women. IF you believe that men and women are equally as agressive, you do not understand human nature.
Believe me, I have worked in a hospital for 25 years. I see these things. I do not buy into the Feminist arguments. I buy into reality, which is what MOST conserveratives do, or should do. Liberals see things as they wish to see them, that is a hallmark of liberalism. That is something I believe you are doing here.
I do not like the fact that men are this way, but I am not embarrased by it, it is human nature and I believe that man has control over his innate nature. We are not slaves of it and can master it. But I am not going to close my eyes to reality. You shouldn't either.
Men are (for obvious reasons) less likely to seek medical attention or call the cops unless the injury is incapacitating. Plus, being generally larger and stronger (I said generally - don't flame me), an equivalent amount of force will cause greater damage to a woman than a man.
Doesn't mean the women aren't trying!
After you finish patting yourself on the back for working in a hospital, go read some actual data-based research on the occurrence of domestic violence. And pay attention to the fact that many male victims not only do not report assaults, or seek treatment when they should, but also lie about the source of their injuries, out of shame, when they do go for treatment.
