Your premise is wrong from the start. Our closest living relatives (Bonobos) have a very female-dominant society, so to just suggest that CLEARLY we are a male-dominant species is flawed without addressing that point.
It's hard to argue with you, not because there's no argument to be made against it, but just because your premise is so off base...
Not always. I'm bigger than almost all males I know (bigger muscles, bigger frame, taller), and I'm not that much of an outlier among females. Humans don't have that much in the way of difference between males and females. And any difference that we do have is easily overcome.
There are many, many more exceptions than bonobos, bonobos just also happen to be our closest living relatives.
Plus your OP is just reinforcing all the negative stereotypes out there about people in my field...
(also, no offense ment but I suggest you stop signing your posts, that's what a signature is for and you can create one that will automatically attach. Actually posting it at the bottom of each post outside of a signature makes it sound pompus and jackassy rather than classy and polite)
Again, it's significantly underreported. Although men still do a lot of the more damaging violence, women are pretty tough themselves. And as far as instigation is concerned, it is much more closer to a 50-50 ratio than 95-5.
Fewer women go to jail because of sexist people like you who insist that males are more violent and harmful. Therefore, abusive women are often treated like victims and don't get in trouble for it. If people like you would recognize facts rather than sexist stereotypes, maybe the world would have a better time combating domestic abuse against men.
