" Among the leading purveyors of Holocaust denial arguments are far-right, neo-Nazi, and white power groups. Their adulation of Nazi ideology, “Aryan” superiority, and, above all, Adolf Hitler make them perfect candidates for denial. They are masters of inconsistency. They argue that murdering the Jews would have been entirely justified but that it never happened. I suppose you could call this the “no, but” argument: “No, it didn’t happen. But it should have. "
