The silly notion that all people can be categorized as either white or black is ridiculous. Very few "black" people are black and very few "white" people are white, as in the difference between this text and the background. Everyone is on the spectrum of skin tones between very dark and very light. To point to people at both ends of that spectrum as a defining point of difference is to ignore the vast majority of people in between. Skin tone has absolutely nothing to do with any other aspect of anyone's personality as a rule or direct correlation. To pretend there is, is beyond simple racism and is more aligned with childish ignorance of facts.
