. . . argue about the scientific validity of race-related IQ differences, the Moderate Voice
links to this "great, serious" race versus racialism debate. Part I is here
I waded it through it, and all it basically did for me is confirm my impression that the scientific community is about a million miles away from a consensus that there is a hereditable connection between race and intelligence. So until someone can come up with a bunch of solid, peer reviewed studies proving such a relationship (There are around a 1,000 or more studies confirming both global warming and the contribution of human activities to it, for instance.), I just think non-scientists should shut up about it.
UPDATE: I should probably point out that The Objectivist (these debates take place between opponents called "The Objectivist" and "The Constructionist.") has also made what I consider a truly idiotic argument in favor of teaching intelligent design in schools here
. If you want to preface lessons on evolution with a disclaimer along the lines of "lots of people believe lots of different things about creation and you're free to believe what you want, but, evolutionary theory represents about as close to a scientific consensus as you're ever going to find," fine by me. But teaching ID as though its actually a scientific theory is just stupid. And I'm not much more impressed with his arguments in favor of "racialism," the semi-PC version of racism. So I would classify this as a less than "great" debate.
