That is the “logic” you are going with?
A black man being innocent of a rape he was accused of is a manipulation of racial stereotypes in an absurd way?
I suppose if the fictional black man was guilty of the fictional rape it would be less absurd in your world view.
It seems that guilt by racial association is the only “logic” behind what you find absurd. I find your illogical assumptions to be absurd.
So the great absurdity you want to warn people against is that a black man might actually be innocent of a crime he was accused of? Or is it that if a white woman doesn't instantly assume that any black man is a likely rapist of white women, she will be in “deep kimchee”?
