That is the very definition of race. That is what the term means.
I think there are a number of people on LW who will dispute that; who will say something like this. "Yes, there are fuzzy popular uses of the word and if you take them too seriously you will say silly things. But it is also the case that there are important genetic differences between human subpopulations, and that these correlate to some extent with those fuzzy popular ideas about race."
That seems to me to be a position that is not at all refuted by saying that popular use of "race" is fuzzy and that the things commonly called "races" don't correspond to well defined biological groupings. (It might be refuted by other means, but that would be more work.)
The most recent post in December's Stupid Questions article is from the 11th.
I suppose as the article's been pushed further down the list of new articles, it's had less exposure, so here's another one for the rest of December.
Plus I have a few questions, so I'll get it kicked off.
It was said in the last one, and it's good advice, I think:
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
