Liberals think Obama is lighter than he is, conservatives think he's darker. Or some such. I looked at the pictures and it looked like "brightness" issue as opposed to dark-skin/light-skin issue. I don't know.
Look, you know me: I'll never undersell the significance of racism in human beings, and specifically the power of anti-black racism in America. It's as old as the country. Having said that, I don't know what to make of this study. I guess there are people who don't think racism is much of a force in American life. I doubt that this will change that. For my purposes, I'm pretty much done with debating them anyway. We overrate "dialouge," "conversation" and "debate."
