I suppose one good reason that revisionists take Wiesel so seriously is that he is a formidable enemy of theirs, and the wide world takes him very seriously indeed.
The revisionist concentrate on Wiesel because he IS the holohoax embodied. He is not a random degenerate, he received the Nobel Peace Prize, the was the first director of the USHMM hoax museum. And he is the public face of the holohoax.
Beyond that, he embodies everything that is incredible about the hoax. His lies are blatant and prima facie absurd. He says the German machine gunners through babies into the air and used them as targets, and no one blinks an eye.
Beyond even that, his lies don't even conform to the official narrative of the holohoax: he says that the Nazis killed the Jews at Auschwitz not by gassing them but by throwing them into burning pits, one for adults one for babies. You have to read this stuff, in 'Night', to realize how preposterous it is. And no one calls him on the fact that the story is first prima facie absurd, and second, not even in agreement with the official version of the hoax.
By all rational thought processes that I can muster, the holohoax establishment should run at full speed from Wiesel, but they don't, they thrust him forward. The hoax is absolutely amazing in its total disregard not only for the truth, but for even any semblance of rationality.
And yet this guy establishes a foundation that every year makes awards for ethics and humanitarianism. It can't get any more freaking absurd.
And yet, we're on the outside, and he is having dinner with Presidents.
