Well, technically we all have some since we are all out Africa. The curious thing is why skin color ever became an issue. When I was growing up, my parents' racism baffled me. I got into a loud argument about it with my mom when I was in middle school. I paraded more than a few Black friends through my home, not out of protest, but because they were my friends.

Science is clear on this (as you know). Melanin was reduced in people who moved north because humans didn't need as much protection against sunlight. If you moved all the Europeans back to Africa, in a thousand years they'd all be black again. Gosh, these people are stupid.
