From PZ Myers:
There is also the part where Harris declares that he has black friends, therefore you can’t accuse him of casual racism. The part where he reveals that he knows nothing about Charles Murray’s work outside of The Bell Curve and can’t comprehend how anyone can think he has racist motivations. But mainly, Harris is all about how others have dared to criticize Sam Harris.
I think it’s damning enough that Harris thinks so highly of himself that he would walk unarmed into a duel with Ezra Klein, and get fairly and politely slaughtered on all points.
Of course, Harris probably emerged thinking that Klein never even touched him.
