And they say blacks are afraid because of white supremacists killing them. Absolutely ridiculous, in reality it's whites who are afraid and blacks worry about other blacks. And is there no difference in aggression levels of black vs white women, and if there is is it all cultural, nothing to do with genes? Genes of course affect impulsivity and consideration of consequences. Racist studies say even in kids you can see a difference in time preference between blacks and whites, for example in the classic test of giving one piece of candy now vs waiting and getting 3 pieces. More black children choose the former, can't handle delayed gratification.
