The "Holocau$t Industry" desperately tries to link this program with the false claim of 'gassings' by the Germans, as if the euthanasia program evolved into the impossible gassings claim.
Have a look at this new piece by John Wear and see another nail driven into the '6M Jews, 5M other, & gas chambers' coffin.
I copied below the conclusion as the entire article is a bit lengthy, take the link and get the facts.
I also suggest using the search function here for euthanasia, there's tons more.
Evidence for the German Euthanasia Program Compared to the Holocaust
By John Wear
Inconvenient History, vol. 9, no. 3, 2017
Euthanasia Poster, ca. 1938
The German euthanasia program is a well-documented reality. Hitler authorized the euthanasia program in writing, the defendants at the Doctors’ Trial admitted their involvement in the program, the best method for killing victims was discussed among the participants in the program, the carbon monoxide gas used in the German euthanasia program can safely and effectively kill people, and the euthanasia program was widely known by the German public. In fact, public opposition to the program was so strong in Germany that Hitler ordered the end of the first phase of the euthanasia program in August 1941.
By contrast, the genocide of European Jewry is not well documented. No order has ever been found authorizing the mass murder of Europe’s Jews. The German defendants at the main Nuremberg trial all stated they knew nothing about the so-called Holocaust. The Holocaust story absurdly states that the first gas chambers were built at Auschwitz using Zyklon B by SS personnel with no engineering experience. None of the alleged homicidal gas chambers at Auschwitz, Birkenau, and Majdanek or the claimed diesel gas chambers at the Aktion Reinhardt camps of Treblinka, Belzec, and Sobibor could possibly have been used for mass murder. The alleged genocide of Jews was also not known by the German public during the war. The eyewitness testimony to the so-called Holocaust has consistently proven to be extremely unreliable. Finally, the large number of Jewish survivors at the end of the war makes impossible a program of genocide against European Jewry.
In conclusion, while the German euthanasia program is a well-documented reality, the Holocaust story is a fraud. Dr. Arthur Robert Butz has aptly stated:
The ‘Holocaust’ is such a gigantic fraud that it is a cornucopia of absurdities.”
The "Holocau$t Industry" in court:
'Please your honor, there really are remains of millions buried in huge mass graves, we know where the mass graves are, ... but, but, well, umm, we can't show the court. You must trust us, we're Zionists.'
