Would it change your position towards the US Republican Establishment if it were shown that "Nazi gas chambers" were completely a fiction of Soviet, British, and US propaganda?

No, because I already know that the World Wars were exactly what they were portrayed as: a seizure of power by Leftist forces fighting advance democracy and smash down elements of older power. World War II was an extension of the Napoleonic Wars.

Regarding the Holocaust, I see the official number has tumbled from six million to somewhere around four million. I also note that most of the killings occurred outside German territory by non-Germans, mostly in the Baltics and Eastern Europe where Jews were blamed for Communism because of their high participation in it.

I also see this stack of data:

It cannot be denied that the relatively small Jewish population of the Weimar Republic posed an objective social problem to the German people. A third of the entire Jewish population lived in Berlin. “The average Jewish household income was three times that of the average Gentile family.” Over 75% earned a living from “trade, commerce, finance and the professions. While nearly a third of Germans worked on the land, barely 2% of Jews were farmers.” German farmers were nevertheless beholden to Jews because “the Jewish grain merchant and cattle dealer were ubiquitous in rural areas.” Jews “owned 40% of wholesale textile firms and fully two-thirds of wholesale and retail clothing outlets.” Almost 80% of department store turnover went into Jewish hands, and “Jews dominated the publishing industry.” Jews comprised “11% of Germany’s doctors, 13% of its attorneys and 16% of its lawyers.” In addition to this population of semi-assimilated, ascendant Jews, was a population of around 100,000 Ostjuden that were widely associated with importing “crime, vice, disease, and the spread of revolutionary ideas” from the East.

I have always believed Albert Speer that the German camps were part of a work program. The fact that all of the corpses appeared starved and diseased supports this and works against the idea of trains showing up and dumping Jews into gas chambers.

But, in my view, none of this matters.

If a population of the Other is under your care, you may deport them and exclude them from your society, but when you start to make them into the Enemy, you have set up the groundwork for mass murder.

It is fine and normal to say "Germany for Germans" but when that becomes "...by removing The Infernal Jew" then you have gone down the path of scapegoating, and that always ends in murder.

Something happened to Jews under German care. It should not have happened. I think we can all agree on that, and should not look further into this lugubrious issue.

We should also consider that world Leftism has been attempting to genocide Germans and every other unique ethnic population for several centuries. If the Germans had confined themselves to locking up Leftists and gassing them, we would celebrate that today.
