This is a long overdue take-down:
The start of the D'Souza phenomenon came in 1995, when he published The End of Racism. Written to ride the wave of books and articles that called for white America to get over its racial guilt, it included lines like the "American slave was treated like property, which is to say, pretty well." It was so sloppy and unconvincing that it killed the genre for a few years; it's a 700-page doorstop by a one-time AEI scholar that no one cites today. The next D'Souza implosion came in 2007, with the publication of another book that killed its genre. The Enemy at Home consisted of an argument that the "left" was responsible for the 9/11 attacks. That was an irresistible hook for a publisher, especially after the public had turned on the Bush administration and the war on terror. But D'Souza made such a hash out of it that the people who had danced around the left-and-9/11 idea realized how deeply stupid it was. Victor Davis Hanson joined the mob and pointed out, as politely as he could, that D'Souza's enemies list was "nonsensical."
So The Roots of Obama's Rage is D'Souza's third pseudo-academic swing for the fences. In the book, and in the Forbes article that Gingrich plans to spread far and wide, he strikes out.
Yglesias concurs and elaborates. Here's my review of D'Souza's last piece of excrescence, for what it's worth. Don't miss Robert A. George's D'Souzaing of D'Souza. And DiA echoes this theme. What still staggers me is that either D'Souza or Gingrich are regarded in any way as "thinkers". They are not. They are self-promoting charlatans, with not an ounce of decency, personal or professional, between them, who see ideas as weapons to be used, or sources for personal advancement and enrichment.
