Yeah they'll give that to native peoples.
Being raised in a white racist culture I too fell prey to the notion that Black people are inferior, save on the athletic field. The reasons are complex and I no longer feel that way, because I learned more that what our society shoves into our face 24/7.
Now if I were a white person, born in a culture that reinforces white supremacy, and the marginalizes Black people, I imagine it would be even harder, for a white person, to dispense with the notion of white superiority. Besides, what would be the incentive?
As I learned, travelled, and understood more I know white people are not intellectually superior to Black people. The science tells us this as well.
The presence of a "Greg," regardless of their motivation or phenotypical characteristics, is a direct result of a white racist society. Indeed that is who Greg is: the manifestation of a white racist society.
