The real definition of Holocaust denial has to do with the logistics of cremation, forensics of the gas chamber, demographics, credibility of the witnesses and tortured confessors. We shouldn't be discussing "history" but science & logistics.
I proposed to define Holocaust denial like this:
The forensics of the alleged murder weapon
Logistics of cremating or disposing of the dead (up to 10,000/day at Auschwitz during the Hungarian evacuation);
The necessary amount of fuel to cremate corpses (every crematory manufacturer says how many kilo calories their retort consumes/hour . . . Where are the requisitions for this amount of fuel?)
The necessary amount of time to cremate a body (is it 20 minutes, as alleged or an hour, which is more realistic)
The type of gas allegedly used (Hydrogen Cyanide ZyklonB louse disinfestant at Auschwitz; diesel exhaust at Treblinka)
The practicality or possibility of using louse disinfestant or diesel exhaust (i.e., diesel exhaust does not have toxic amounts of carbon monoxide; some "witnesses" say the Zyklon was "swept out the doors" and dumped through holes in the ceiling)
Aerial reconnaissance photos, which contradict eyewitness testimony of smoke & flames belching from crematoria chimneys and shows no huge piles of coke necessary for mass cremation above those that died during typhus epidemics or other causes;
Tortured confessors, malicious and absurd "eyewitnesses" (the reliability of witnesses or confessions and hearsay)
The reliability, translation and context of the evidence/documents
Demographics (were 6,000,000 killed?)
The practicality or possibility of cremating bodies in pits, the lack of evidence that any pits were dug (can't see 'em in the aerial reconnaissance photos) . . . etc.
This is what H-denial is. Raquel Baranow (talk) 01:30, 10 March 2009 (UTC)
Wikipedia editors censored the diesel exhaust reference in the Gas Chamber article. Diesel exhaust has inert amounts of carbon monoxide.
My 9/11 argument with Wikipedia dealt with the tiny debris pile at ground zero made up of only steel beams, everything else was pulverized into dust, which fell several inches thick all over lower Manhattan, sickening clean-up crews. What kind of bomb could have done this? At the time, I thought it was a thermobaric bomb but now there's scientific evidence that thermite was used.
