I know I will get shit for this, but I believe the holobunga actually happened. I just think it was more typhus and starvation than gas and ovens. I believe Jews are neurotic and they over sensationalized parts of it because they wanted to be believed above all else even at the cost of realism. I'm also not so sure about the numbers, but that's something I'll be an agnostic about.
Some jews probably did perish in the camps during the bombing runs on supply lines or after the Allies took over the camps. The Holocaust never happened because there was never a systemic campaign to wipe out all Jews by the German people. When the Jews say the holocaust happened, that is what they mean, and that is what they have been using as their excuse to "punish" whites and spread weimar degeneracy and advance the Kalergi plan.
