Ponder, for a moment, how dumb racism is. It's all about skin color. Skin. Color. A physical trait, like being tall or short. In fact, race doesn't even really exist. It's an artificial construct that arose to keep human beings divided and foster an "us vs. them" mentality.
Being black or brown doesn't make someone an inferior human or "marked by God" or whatever racists say it means. Having dark skin means your people lived in places with abundant sun & needed higher levels of melanin to protect themselves from the sun. That's it. That's all it is.
But of course, stupid people, which racists are, don't believe in science.
