Tom Metzger and of the Holocaust deniers Willis Carto, David Irving, Ernst Zündel, and Herman Otten. Hoffman was the Assistant Director of the Institute for Historical Review (!HR), a Holocaust denial organization for a period. He retains a connection with it. Stephen A. Atkins, in his book, Holocaust Denial as an International Movement (2009), wrote that Hoffman's newsletter Revisionist History promotes Holocaust denial and Hoffman contends that "the real Holocaust of World War II was deaths caused by the Allies." He quotes Hoffman denying the existence of gas chambers: The Great Holocaust Trial: The Landmark Battle for the Right to Doubt the West's Most Sacred Relic (1985) is a sympathetic account of the 1980s Canadian trials of Ernst Zündel.

According to Derrick Jensen, Hoffman is "overtly racist" and "attempts to make the case that the enslavement of whites by commercial interests in Britain and the Americas was worse than the enslavement and genocide of Africans... perpetrated by those same interests." Jensen said "Hoffman's analysis is seriously flawed" but that "his scholarship is impressive, and the story he tells is both interesting and horrifying". The book's espousal of the Irish slaves myth is considered by Liam Hogan (interviewed by the Southern Poverty Law Center in 2016) to be responsible for the notion being absorbed by white supremacists. Cryptocracy Hoffman is the author of Secret Societies and Psychological Warfare which outlines his conspiracy theory of a shadow government or "cryptocracy" that gains power through manipulation of symbols and twilight language. Examples of such "psychodramas," in Hoffman's view, include Route 66 (which connects
