Michael Bellesiles, the historian who resigned his professorship last month after a panel of his peers concluded that he had made up much of the information and many of the sources for his controversial book on the history of guns in America, remains defiant about his scholarship, insisting that his facts are good, and that he was not motivated by anti-gun political leanings. He denies that Emory University paid him off to go quietly, and continues to carry on a vigorous e-mail debate with some of his sharpest critics.
