I highly respect David Cole and his work. His documentary is one of the things that started revisionism in the English world(The Hoax of the Twentieth Century and the Leuchter & Rudolf Reports were the only significant works before this), and it's impact actually led to the Auschwitz Museum making changes to the exhibition. David left revisionism in 2000 but remained true to his stance. Unfortunately, he's become an aggressive person against anyone who disagrees with his belief that the Operation Reinhard camps and Chelmno were death camps. This has been debunked thoroughly by revisionists - Holocaust Handbooks volumes 8,9,19,28 for Treblinka, Sobibor, and Belzec. Volumes 23 and 26 for Chelmno and the gas vans. One Third of the Holocaust(made by Denierbud), and The Jewish as Chamber Hoax & The Treblinka Archaeology Hoax(Eric Hunt).

Cole's reasoning is based on The Goebbel's Diaries, Korherr Report, and the Hofle Telegram. Apparently, if you disagree with his version of history, you're a denier. This notion is absolutely absurd, because even if you only believe those 4 camps were used for mass murder and not the others, you'd essentially be denying the purpose of the other 2 camps. Even though different people hold different views, it doesn't mean they're deniers. Revisionists do what they claim - revise history into a correct version. David's bias and hatred is obnoxious and blatantly obvious.
