The point made in this article is that in the 1980s or '90s, the Simon Wiesenthal Center reduced the number of dead jews just at Auschwitz by more than 2M. This 100% jew-owned and -operated center is the de facto bottom line authority on the jewish version of the history of the holocaust. The reason one is able to infer that the story about the 6,000,000 must be bullshit, which is to say that the story about the "holocaust" must be bullshit, is that the numbers said to add up to 6M before this revision are still said to add up to 6M after subtracting 2M. Keep in mind that this is a revision *only* to the numbers at Auschwitz so one expects that all of the camps were overcounted and the 4M which is never cited would still be a gross exaggeration.
