I can find the female on male murder rate for most countries quite easily, and if it's not recorded, the number of women arrested for murder.
No such data is available for Ukraine - is that really the case? Or is it being hidden to keep people from rejecting the "refugees"?
Same reason why women in the US scream about killing all men but recoil at the idea of being drafted.
They don't like their targets to know they're being targeted.
Edit : Definitely hit a nerve here.
