It's a flight of fancy to expect men ever to do anything that isn't entirely in their own interests. So just as we'll never be able to get crime down to the mythical 4% we'll probably never get it very much lower than it is now because men can't be bothered to take any measures that might inconvenience them in order to protect women.
This is my last word on this one Patriarchy because it is boring now, I agree. You said:
'I never said it explains male violence, it was a throwaway example of one small aspect of dominance hierarchies and their effect on societies. I was explaining the link between female attraction to masculine stereotypes.'
I never said a word about it explaining male violence. What I said was the notion of women having a choice over mates and therefore having an influence on the value of violence to men is nonsense, given that there has never ever once ever been any time in recorded history (apart from now) when women have had one iota of control over anything - not their own vaginas, not their own children, not their own money or property or any aspect of their own lives. For women to have influenced male competition they would have had to have the freedom to choose and they have never had that. Ever. You positing some nonsense based on primates and paper wasps really annoys me because it totally whitewashes the fact that at every known point in history the main thing that men have done is restrict, trade, buy, sell, rape, maim, abuse, terrorise and kill women. This fantasy land of women choosing mates is ridiculous. And the fudgey answer about aeons of history is nonsense too - why anyone would believe that women had more control in the past is beyond me, given that in the most technologically, socially and economically advanced period of known history women are still struggling to get control over their own lives.
