Reading in the NY Times about James Watson's genome I stumbled on to this:
Professor Church predicted that as the science of genetics advanced, fuzzy categories like race would become less important because genetic characteristics would point to factors like disease at an individual level.
Meanwhile, he said: "There are still a lot of bigots in the world. Maybe showing these things are more nuanced than they'd like it to be makes them think about it."
...right...right...gotcha. 'cause bigotry is so rooted in careful consideration of facts, especially nuanced ones.
