Oh good. So it wasn’t for his hatred of blacks and Jews. Right.
Byrd: [I would] never fight in the armed forces "with a Negro by my side." Byrd added that, "Rather I should die a thousand times, and see old Glory trampled in the dirt never to rise again, than to see this beloved land of ours become degraded by race mongrels, a throwback to the blackest specimen from the wilds.." ..."
... "during the general election campaign, Byrd's GOP opponent uncovered a letter Byrd had handwritten to Green, the KKK Imperial Wizard, recommending a friend as a Kleagle and urging promotion of the Klan throughout the country. The letter was dated 1946 -- long after the time Byrd claimed he had lost interest in the Klan. "The Klan is needed today as never before, and I am anxious to see its rebirth here in West Virginia," Byrd wrote, according to newspaper accounts of that period. Byrd makes no mention of the letter in his new book."
