Over 30 years ago, historian and social critic Deborah Lipstadt wrote a powerful book, Denying the Holocaust, warning the public about the dangers of this pernicious ideology. Before talking about specific deniers—institutions and individuals—Lipstadt announces in her first chapter that she refuses to debate Holocaust deniers. She criticized patriot groups, liberty groups, and even the John Birch Society in the same sentence as discredited Holocaust denial organizations. I know many John Birchers, and they are not hostile to Israel, nor do they traffic in Holocaust denial. After reading Denying the Holocaust, I appreciated Lipstadt calling out the cowardice and collusion of the universities and printing houses.
