I believe there’s an interesting case to be made for a type of ancient communism which seems to have persisted through to the Classical era:

Biblical scholars have argued that the mode of production seen in early Hebrew society was a communitarian domestic one that was akin to primitive communism.[26][27]

The early Church Fathers, like their non-Abrahamic predecessors, maintained that human society had declined to its current state from a now lost egalitarian social order.[28] There are those who view that the early Christian Church, such as that one described in the Acts of the Apostles (specifically Acts 2:44–45 and Acts 4:32–45)[29][28][30] was an early form of communism.[31][32][33] The view is that communism was just Christianity in practice and Jesus Christ was himself a communist.[34] This link was highlighted in one of Marx's early writings which stated: "As Christ is the intermediary unto whom man unburdens all his divinity, all his religious bonds, so the state is the mediator unto which he transfers all his Godlessness, all his human liberty".[34] Furthermore, the Marxist ethos that aims for unity reflects the Christian universalist teaching that humankind is one and that there is only one god who does not discriminate among people.[35] Later historians have supported the reading of early church communities as communistic in structure.[36][37][38]

Pre-Marxist communism was also present in the attempts to establish communistic societies such as those made by the ancient Jewish sects the Essenes[39][40][41] and by the Judean desert sect.[clarification needed][42]

This started when you countered an example of Jewish subversion with the achievements of Einstein.

Can you substantiate how this is 'subversion', let alone 'Jewish subversion'?

Einstein certainly accelerated the development of theoretical physics, but many other people in his field were running in the same direction.

Can you name a few? Not Fitzgerald or Lorenz, who were running in the exact opposite direction.

Whereas in social sciences, for example, social Darwinism was the order of the day until Jewish thinkers like Boaz intervened and turned the bus around to cultural relativism

How very interesting. You don't have a problem with people subverting historic Christian doctrines with such piffle like 'social Darwinism', but you do care about one incorrect idea being displaced by another? Social Darwinism has more in common with cultural relativism than either have with anything that is related to Western civilization.

I would refer you to The role of Jews in the Russian Revolutionary movement by Leonard Schapiro, which plainly states on the first page that 50% of the revolutionary party membership was Jewish.

Well, you're moving the goalposts already. You said that 50% of the leadership of the Bolsheviks was Jewish, and all you presented was a not substantiated claim about the membership of revolutionary parties.

Furthermore, this happened in the summer of 1903, your article says. This was before there even were Bolsheviks, let alone a leadership of Bolsheviks.

There are also contemporary writings from Churchill and other leaders that show they believed the Jews were leading the Bolsheviks.

That's very good and all, but there are actual documents showing who the leaders of the Bolsheviks were. You don't need to quote people, you can just point to the members, right?

Look, obviously Jews were overrepresented among Bolsheviks. But as soon as you made that claim, it being as sweeping as it was vague, I knew that you weren't right about it.

For example, he wrote the role of Jews in the revolution "is certainly a very great one; it probably outweighs all others."

The irony is that the two Jewish members of the Politburo I know of voted against the October coup d'etat.
