What I don't get is how feminists seem to think it's a great revelation that men are more violent. A well kept secret that needs communicated to the masses.
Plot twist. Everyone already knows, because it's the same with the vast majority of mammals on this planet. Bulls are more aggressive than cows. Rams are more aggressive than ewes, etc etc. Human males are more aggressive than human females and commit much more violence, the vast majority of which is against each other as in the animal kingdom.
The difference is that most feminists seem to believe that humans are a unique case rather than being like pretty much every mammal out there, including our ancestors. Most seem to strongly refute that it has anything to do with testosterone (despite the reams of studies) and usually try and argue it's to do with socialisation or privilege etc.
I'm not sure why this is but I speculate it may be because it's a tough battle when the enemy is nature rather than men. If we blame it on men then we can lump them all together and lecture the 99% of men that don't murder. When they point out that they're non violent and haven't ever killed a women then we can say "oo, but we can't tell the bad ones from the good".
