I know some people are born into these mindsets. I know what it’s like to have been raised by a bigot; indoctrinated thoughts are the hardest to change.

Could it be that racism creates conditions which lead to a higher frequency of situations which will reinforce racist stereotypes? Too much thinking involved, it makes more sense that the blacks are inherently different.
