You may be right, but my point was the ideas he brought up merited discussion. The social timing of it may be what caused it to blow up so much (that and the misrepresentation by Gizmodo), but at least personally, I had not heard the argument made before in a way that allowed it to be discussed as widely as it is.
As some one who took a sociology 101 class in junior college... nothing in his memo is original/new/insightful. This is a classic nature vs nurture argument.
