Denying History takes a bold and in-depth look at those who say the Holocaust never happened and explores the motivations behind such claims . . . Uncovering a complex social movement, the authors go much deeper than ever before not only in understanding the motives of the Holocaust deniers, but also in refuting their points one by one. In the process, they show how we can by certain that the Holocaust happened as it did and, for that matter, how we can confirm any historical event.
