The only thing about the "Holocaust" that was some kind of record was how fast it went. And the figure that is always mentioned, 6 millions, is probably too high. Maybe 1 or 2 millions, at most 4. Fact is, it's not even proved that most Jews who died were gased, even if they of course were treated extremely badly. Of course there were concentration camps. Of course they starved, froze and suffered from diseases. Of course many actually were gased, on occasions. But they mostly did that with carbon monoxide and carbon dioxide from trucks, not from cyanide. Zyclon B existed, though. It was a chemical, ironically called Prussian acid or blue acid, which was used to exterminate bugs. But 5 millions Poles died. 20(!) millions Russians. And at least 4 millions Germans, many of them civilians who hadn't voted for Hitler or knew what they had voted for.
