No deflection attempted; I don't have a horse in this race. I know exactly who Dr. Gates is (and he lives about ½ mile from me in Cambridge, Massachusetts). He is, indeed, a respected scholar. And his opinion has great validity; although if he really does disagree with what the U.S. Census has reported, then some further analysis may be indicated.
In any case, I didn't mention Dr Gates; my comment was directed at the publication cited, the Federal Observer (and Jeff Bennett indirectly). Given that Dr. Gates' article is widely available from numerous respected sources, I thought it interesting that the Observer was the source cited. It's hardly known as a scholarly and objective publication.
