What’s your explanation for the fact that men commit 90% of the violence?
Childhood trauma, and given that women kill and hit more children than men do coupled with the fact that little boys are more likely to be physically disciplined than little girls I think that sets up an extremely dysfunctional attitude towards women in these little boys minds as they grow into men.
I'd also point at the CDC figures for intimate partner violence within lesbian relationships places it at a significantly higher proportion than women in hetererosexual relationships. With gay men being the least likely. I'm not sure how lesbian violence can be men's fault.
Of course given that men have a 15-20% strength/size differential from women the damage they inflict will likely be more severe and more likely to be fatal. However I think the misandrist myth that men are responsible for all violence is innacurrate and dangerous.
What is shown is that often humans with a size/strength differential will abuse those smaller and weaker than they are, child abuse statistics reduce each given year as children get older and bigger. So a child is more likely to be murdered at 1yr old than 10yrs, and so on.
The good news is that we can track an overall reduction of human violence across the decades that correlates with the reduction of hitting children.
In the meantime I'm totally in favour of targeting men for anger management programs, as they are the ones more likely to able to inflict worse damage, with an eye to ensure the next generation are free from the blight of violence, but I don't think trying to blame it all on men will get us all the way there I'm afraid.
