Are you sure? I do.
Not to the extent of violence or hatred, and I don't even use my difference for making points. But my pigment does play a part in my center. I try to use common sense over raw emotion though. I use my bias for choices that either please or are beneficial to me, not for frustration or violence, or hatred. Even white people have preferences of other white people based on appearance, same goes for all races.
Ever notice how people who look alike tend to flock together in the lunch room or at parties? Wonder how with so many species of animals that are in the same gene pool tend to not mix based on physical features?
I always found it amazing that when chickens are allowed to free roam, that the chickens that look alike flock together. Keep in mind they have no mirrors to know, but they seem to know. So you may not make choices based on pigment, or you may use your pigment to make intelligent wise choices.
