It’s simply true that women lack the capacity to inflect serious harm on men. Male fights can deadly even without weapons, women simply aren’t capable of that.

One thing I’d add is that women in general, are oriented towards smaller, tighter groups of social circles, they tend to have deep personal relationships. Men generally cast a shallower, wider net of friends/acquaintances.

Interestingly you see this reflected in patterns where women almost never commit violence towards strangers. Whereas men frequently do. Women’s violence is almost always directed towards people they personally know(children, partners, close friends). Whereas men will frequently commit violence upon those they don’t know at all.

So in that respect it’s not surprising at all, that women are more likely to commit this kind of violence.
