There have been numerous studies into the psychological aggression in relationships, and they seem to indicate that women are more psychologically abusive then men. Such as this study here: http://www.psicothema.com/pdf/3334.pdf
Aggression is not a gender determinant trait however, we are all humans, and we all have aggression that gets expressed in their own ways. Other studies done by other research centers found the rates of aggression in older couples to be pretty much dead even, so even when the results don't show women abuse more then men, women still abuse.
It's just a fact of our species, so why deny it or not embrace it?
...Interesting, but that only touches on domestic violence. And it acknowledges that when males do it, it has a greater impact on women's health, which is why we take domestic abuse by men a lot more seriously, for better or worse. But that leaves aside all the other kinds of violent crime which are skewed toward male perpetrators.
Regardless, looking at where this discussion has gone. You have to defend the notion that women can be just as wrathful/violent/etc, just in more oblique/psychological ways. We take violence against women much more seriously than the reverse. Doesn't that implicitly acknowledge that there is, in fact, a stereotype that says men are the more violent gender? Whether it's true or not is something we can debate, but it does exist. That was the main thing I was getting at.
