I think most of theories of them is CRAP.
Basically,they always claim "peaceful female and violence male",I think it's nonsense.
Just because the target of female violence usually is very weak and can't not resist and talk,I think they just good at calculate the success rate of their violence.
Here is some examples:
I googled picture keyword "fur",most of people wearing it are female.
Oh,most of infanticide criminals are female.And these victims can't talk. I usually heard locale news about "found dead rotten infant body"...I guess this time I don't post than image is better than I post.
Personally,I met a lot of verbal violence and insult by those people who claim themselves are feminists just because I don't want to join into them.Even Muslims didn't act like that way.
I am such a traitor...bah!
I am very sure the verbal violence by female far more than verbal violence by male.
Based on my personal values and these evidence,I don't think female is "peaceful".
I know some of authoritarian countries,like Russia,North Korea,China,most female in these countries like their authoritarian regimes much more than male...
I found a logic issue,the human education system is controlled by female more than male.The mothers,kindergarten/primary school teachers,if they are suppose the values of gender equality,they should instill their gender equality values to children,but I didn't see that way.
Reminding those authoritarian regimes...
