Hm. I hear people who keep saying race is a social construct, but there are defined genetic differences between Mongoloid, Caucasoid, and Negroid races that distinguish them as races. That's science, not social construction.

Science says we're different. It's people who then start ranking those differences (with themselves at the top, of course). It's one of the reasons I hate hearing racists or sexists quote science and then mangle it into "proving" they're superior. Science doesn't say any race or gender is superior because science is facts, not ego.
