It all depends on who you ask. In the eyes of anyone who has grown up living on Zionist propaganda since birth even a well respected historian will become a nut job if he simply states a historical fact which goes against all of the propaganda brainwashing: that no scientific evidence exists that Jews were gassed.
This is particularly true about British Historian David Irving, French Historian Robert Faurisson (if you speak and understand French, do look into him), and other blacklisted academics and historian, who mind you, are some of the best historians and experts on WW2 era. Their only wrong? That they question the official holocaust narrative.
As long as the mainstream remains under the domination of a certain interested party these historical facts will remain suppressed and anyone who tries to bring these historical facts into the mainstream will be discredited, sidelined, and labeled a "nut job", "anti-semite", "holocaust denier", etc before he/she even gets a chance to convey the message to the masses, and the masses will readily swallow the media lies about the person.
Anyhow, here is some info that might interest you both
@Nefer :
"When American and British forces overran western and central Germany in the spring of 1945, they were followed by troops charged with discovering and securing any evidence of German war crimes.
Among them was Dr. Charles Larson, one of America's leading forensic pathologists, who was assigned to the US Army's Judge Advocate General's Department. As part of a US War Crimes Investigation Team,
Dr. Larson performed autopsies at Dachau and some twenty other German camps, examining on some days more than 100 corpses. After his grim work at Dachau, he was questioned for three days by US Army prosecutors. [1]
Dr. Larson's findings? In an 1980 newspaper interview he said:
"What we've heard is that six million Jews were exterminated. Part of that is a hoax." [2] And what part was the hoax? Dr. Larson, who told his biographer that to his knowledge he "was the only forensic pathologist on duty in the entire European Theater" of Allied military operations, [3] confirmed that
"never was a case of poison gas uncovered." [4]

The Liberation of the Camps: Facts vs. Lies
Its almost like they planned all of this propaganda before hand and just continued it after the war. And the sad part of it all: the masses swallowed it all whole. The same 6 million number was used before against the Russian Czarist gov.t and the White Russians prior to the advent of Hitler and the Third Reich.
Jew and Holocaust Scholar Raul Hillberg forced to admit in a Toronto, Canadian court that there is no scientific evidence proving Jews were gassed:
Official Auschwitz death toll number changes overnight, how did 2.5 million dead people disappear from the death toll overnight??
BTW, all of the SS camp guard confessions were extracted through torture, thus they are not reliable evidence that Jews were gassed in the concentration camps:
The Nuremberg Trials (part 2)
How Britain Tortured Nazi POW's During Interrogations- The Daily Mail
How the British Obtained the Confessions of Rudolf Höss
There's more, but i don't want to overwhelm you. For now this should suffice though.
