White nationalists, learning yesterday of activist Derek Black’s renouncing of the movement, reacted with disbelief, conspiracy theories and unbridled fury. But it was the fact that Black, son of the former Alabama Klan leader who now runs the largest racist Web forum in the world, made his comments to the Southern Poverty Law Center that seemed to be the single factor that most rankled the racist world.

The reaction that may have been the most noticed came from Don Black, who expressed his shock about his son’s comments on his Stormfront blog. “Derek was here all weekend, helping us build and replace old windows” at the family home in West Palm Beach, Fla., the elder Black wrote. “He’s made it annoyingly obvious over the past few months he was no longer interested in WN [white nationalist] activism, but he always said he was still WN. I knew the Jews at the Poverty Palace [SPLC] were working hard, since he would be such a big prize for them.

“But he didn’t give us a clue as to what he planned today.”

“I don’t want to talk to him, but his big sister called him, and he confirmed that he had written what the SPLC posted,” Black added. “He says he doesn’t understand why we’d feel betrayed just because he announced his ‘personal beliefs’ to our worst enemies. Oh well. Just when I thought I couldn’t lose anything else.”

“Maxfield Parrish” didn’t hold back. “He is a traitor, one without hope and one without redemption,” he said of Derek Black, 24. “Should WN’s ever seize power his name should figure prominently on the ‘Hunt Down List.’”On Vanguard News Network (VNN), another racist Web forum, one Leonard Rouse sounded similar. “He sent an email, meant for publication, to his worst enemy, repudiating everything he formerly stood for and that his father claimed and claims to stand for. …. I want to give people the benefit of the doubt, but Jesus.”

Others were far harsher. On the white nationalist Occidental Dissent website, “Maxfield Parrish” didn’t hold back. “He is a traitor, one without hope and one without redemption,” he said of Derek Black, 24. “Should WN’s ever seize power his name should figure prominently on the ‘Hunt Down List.’” Parrish went to describe how the younger Black should be “softened up with brass knuckles to the face and groin, then water-boarded,” ultimately “reducing him to a quivering, gelatinous lump of obedient flesh,” before being exiled to Africa.

“He is now an open enemy of the survival of the race,” said a VNN posting from “N.B. Forrest” — a reference to Nathan Bedford Forrest, an antebellum owner of a major slaveyard, Civil War general and first national leader of the Ku Klux Klan.
