Rape is impulsive, inability to control a primitive urge
Whites are not so impulsive. We plan long term how to survive winters. Blacks lived by equator where they could climb trees for coconuts. They did not have to plan ahead. Impulsive. Like dogs in heat.
I can tell you this from first hand experience of working, and living around blacks, there is a shit ton of unreported everything, but especially rape, and domestic violence in general.
