"The enormous advances in genome studies have effectively discredited the whole idea of "race" as a means of categorizing humans. And however ethnicity may be defined or subdivided, it is utterly unscientific and retrograde to confuse it with color. The number of subjective definitions of "racist" is almost infinite but the only objective definition of the word is "one who believes that there are human races.""
Obviously, Hitchens is an ignoramus about genome studies. It's fascinating how Hitch, America's most famous atheist, has made a tenet of religious faith out of a scientific theory -- and a wrong scientific theory, at that! As a G.K. Chesterton scholar summarized, when a man stops believing in God, he doesn't believe in nothing, he believes in anything.
Moreover, this is revealing for the lack of self-awareness that political correctness induces. Hitchens is America's most famous atheist and used to call himself, in his cups, "the world's biggest anti-Semite," yet his entire life was turned inside out -- to the point that he now drops by synagogues -- when he discovered his mother was part-Jewish. Hitchens' own life betrays the falsity of Hitchens' theory.
