Bullshit feigned outrage at a straightforward response to a goading OP. You know very well what you were doing, drop the act.
But back to the topic at hand, so you didn't describe what you meant by masculinism[/I This isn't a term I'm familiar with. Looking it up, I see various definitions. It sounds like you are using it to mean "be male", which doesn't seem to conform to the definitions I'm finding online. Which seem to be some sort of feminist-like men's rights movement. Care to clarify?
In any case, my point is that it is a pretty well established fact that males, on average, are more aggressive (although not by much), and more importantly, when they are aggressive, tend to do more physical damage for any given act of aggression (more important and relevant to the topic of domestic violence).
And when I say "males on average", you to be precise, we can imagine that the distribution physically aggressive tendencies in men and women form two bell curves. The mean is higher for men, although the absolute difference is probably not that large (most sex-based differences are small on the scale of average differences). So, there is a ton of overlap in the middle of the curves. However, at the tail end of the most aggressive people, the sort of people that would end up in a maximum security prison, you are looking at almost exclusively males. And in general, this one reason why you find many, many more men in prison for violent crimes. And this disparity is driven by the tail end of very aggressive males.
This is pretty much common knowledge. Again, I'm not even sure what you are talking about in your OP. What is masculinism?.
