Holocaust denial after Irving imploded
Did Irving's implosion in court end the Holocaust denial movement? Obviously not, if you've read this board. But it did signal a sort of changing of the guard.
Holocaust denial initially was a two-fer: a movement to rehabilitate Hitler's reputation as well as a weapon to attack the Jews by mocking and denying their tragedy. The basic lines of song and dance hasn’t changed in fifty years — those four core points that Lipstadt writes on the white board in the first few minutes of the movie went back to the beginning of the movement and are still in play today.
Now, after fifty years of Holocaust denial, it's clear to the deniers that the battle for Hitler’s image is lost. They weren’t able to turn the mainstream tide, and they no longer try (very much). Sure, promoting Holocaust denial means trying to get Uncle Adolf off the hook for one the world's greatest crimes, but that's incidental. Not unwelcome, just incidental.
Instead, Holocaust deniers focus on the other side of the coin: Holocaust denial as a way to attack the Jews. Exposing the “Holohoax” means exposing the treacherous nature of the Jew by unmasking their grandest criminal scheme, a swindle of literally global scale touching every nation on earth, every newspaper, every broadcaster, every publisher, every history department. In conspir-o-sphere form, "Holocaust revisionism" is about a massive international hoax that The Powers That Be Don’t Want You To Know WoooOOOOOoooo.
What this means is that the basic fault line in the Holocaust denial movement -- the question of whether to be overtly anti-Semitic or only tacitly anti-Semitic -- remains in place. Do you do the "I'm just an innocent researcher who just happened to learn there was a swimming pool in Auschwitz, and I'm now wondering whether this negates the entire story we've been told about the Jews in WWII" flavor or do you do the "White man, you must free your mind from the propaganda shackles by which the Jew enslaves you" flavor? Both flavors have shown up on this board.
You don't have to be a neo-Nazi to promote Holocaust denial; you just have to hate the Jews more than you hate the Nazis.
This pivot -- the decision to soft-peddle Uncle Adolf, while continuing to promote the Big Jew Conspiracy theory -- happened about the time of Irving's defeat, about the same time the main Holocaust denial organization internationally (the grandly named hate group, "Institute for Historical Review") went to pieces over infighting.
Since Irving's defeat there's only been one new name worth noticing in the movement: Mahmoud Ahmadinejad. If there's a more complete description of defeat than that, I don't know what it is.
