Sure, I feel like both of your points are addressed by the first paragraph already:

> Jewish Bolshevism, also Judeo–Bolshevism, is an antisemitic, anti-communist conspiracy theory, and myth[2] that claims that a Jewish conspiracy was behind the Russian Revolution of 1917, controlled the Soviet Union and international communist movements, and had a secret plan to control or destroy Western civilization; or, more generally, it is the antisemitic myth that Bolshevism was fundamentally Jewish.[3] It was one of the main Nazi beliefs that served as an ideological justification for the German invasion of the Soviet Union and the Holocaust.[4]

I had a history education in Austria, a big part of it was trying to teach how we ever got to the atrocities that were committed, and as part of that we were thought how the Nazi ideological apparatus worked.

The conflating of Jewishness and Communism was a key pillar of their ideology.

As the citation says, it was one of the main beliefs that justified the invasion and the Holocaust. Even if Jewish Bolshevism wasn't a thing (which could happen, if Jews didn't get better representation in the USSR in comparison to the Empire), Nazis would still commit the holocaust, invade the USSR, and, most importantly, still exist, thus, it can't be called a key pillar of Nazism. It's more accurately described as a key pillar of Nazi propaganda, supported here:

> Michael Kellogg in his Ph.D. thesis argued that the racist ideology of Nazis was to a significant extent influenced by White émigrés in Germany, [...]

p.s. Kellogg is mentioned below to argue that this was the origin of Hitler's antisemitism, but that is contested, and there's plenty of evidence of Hitler antisemitism from early on. Still, Jewish Bolshevism is well accepted as a key propaganda element.

Moving to the second point, I don't see how your citation address it. "Cultural Marxism" is primarily spoken without referring to religion. Unlike Cultural Bolshevism, there's no modern equivalent to Jewish Bolshevism, and, as I stated previously, the ones who primarily talk about Cultural Marxism don't even mention religion, and if they do, they often treat Judaism and Christianity as if they are in the same boat. If anything, the closest religious scapegoats would be Muslims, but they aren't treated as "masterminds". Don't even get started on race (which is what Nazis actually cared about).
