Do you know what rape does to a rape victim? No? Well let me educate you.
It eradicates their sense of self ( https://scholarcommons.usf.edu/cgi/...le.com/&httpsredir=1&article=1180&context=etd ) it fucks with your identity - it makes people husks of their former selfs if its done repeatedly. Its a known 'technique' in war to break societal resistance. It destroys personal and societal identity.
Its often used that way in tribal conflicts (captured and abducted women, that then are being force 'integrated' into other tribes). Rape and destroying cultures often go hand in hand.
Yes, it's horrific. But none of that is what genocide means.
