Specifically the claim that "deniers" assert that Auschwitz did not exist is new to me. The genocide of lesbians (and its denial and the general connection between lesbian genocide denial and anti-semitism) is also a novelty.V. Countering Holocaust denial and the distortion of History
35. Holocaust denial is an attempt to negate the established facts of the Nazi genocide of European Jews, Roma, gays and lesbians as well as political opponents. Key denial assertions include that the murder of approximately six million Jews during the Second World War never occurred, that the Nazis had no official policy or intention to exterminate the Jews, and that the extermination camps such as Auschwitz-Birkenau never existed.
36. The Special Rapporteur recalls that the Holocaust is one of the well-documented events in recent history. Holocaust denial and distortion are generally motivated by strong anti-Semitism, and build on the claim that the Holocaust was invented or exaggerated as part of a plot to advance Jewish interests. That view perpetuates long-standing anti-Semitic prejudices and stereotypes, accusing Jews of conspiracy and world domination and of hateful charges that were instrumental in laying the groundwork for the Holocaust.
