IN 1956, nearly a century after Fort Sumter, Robert Penn Warren went on assignment for Life magazine, traveling throughout the South after the Supreme Court’s school desegregation decisions. Racism was thick, hope thin. Progress, Warren reported, was going to take a while  a long while. “History, like nature, knows no jumps,” he wrote, “except the jump backward, maybe.”

Last week, Virginia’s governor, Robert McDonnell, jumped backward when he issued a proclamation recognizing April as Confederate History Month. In it he celebrated those “who fought for their homes and communities and Commonwealth” and wrote of the importance of understanding “the sacrifices of the Confederate leaders, soldiers and citizens during the period of the Civil War.”

The governor originally chose not to mention slavery in the proclamation, saying he “focused on the ones I thought were most significant for Virginia.” It seems to follow that, at least for Mr. McDonnell, the plight of Virginia’s slaves does not rank among the most significant aspects of the war.

Advertently or not, Mr. McDonnell is working in a long and dispiriting tradition. Efforts to rehabilitate the Southern rebellion frequently come at moments of racial and social stress, and it is revealing that Virginia’s neo-Confederates are refighting the Civil War in 2010. Whitewashing the war is one way for the right  alienated, anxious and angry about the president, health care reform and all manner of threats, mostly imaginary  to express its unease with the Age of Obama, disguising hate as heritage.
