In their crusade against anything Nazi gas chamber-related, deniers use the hyper-skeptical approach: witnesses are right out, documents are suspect and probably forgeries, and don't even mention hearsay or "tortured" confessions.
This approach is utterly ahistorical, as has been demonstrated time and again. But the problem is not even that the deniers use approaches that no historian deems sound. It's that they use them only when they want to deny the Nazi mass murder. When they see an atrocity claim that they actually like, all "skepticism" flies out of the window.
Case in point: the deniers' treatment of the Soviet gas vans story.
