Not really true. Guy apparently can't tell the difference between bad and really, really bad. Between oppression and extermination.
The commies were plenty efficient when really focused on killing a particular group. They killed a much larger number of people in total, but a much smaller number of Jews than the Nazis, which indicates not inefficiency on their part, but rather a much lesser degree of intention to kill Jews, as such. Most Jews in USSR were killed not because they were Jews but because they were enemies of the People for some other reason.
It also should be pointed out that Jews formed a very disproportionate percentage of those who most aggressively supported Communism and helped bring it to power and keep it there.
I think Stalin did go after Jews for being Jews...see the Doctors Plot.....he pretty much blamed most Jewish party members by name for being Bolshie rivals and Trotskyites
This rivalry between Jewish revolutionaries started with their preponderance with Menshies and then Lenin’s cliques and later Trotsky
And Stalin and Beria....Molotov too I guess even though his Jewish wife was imprisoned....all blamed Jewish commies as Jews of a conspiracy against the state....some party member Jews survived but likely renounced anything to do with the religion of their birth
They purged most of them as such...
Russian fellow commies turned on them
Then Fascists blamed them as communists even as commies purged them via that special Stalin disappearing photo technique
It was a severe double whammy for continental Jewry....ironically the Iberian peninsula..... fascist too....was even though not totally innocent....a rare refuge for Jews.....not sure Franco’s reasons for resisting Nazis calls for railcars
Cronos you meant Trotsky
And Stalin had many of them killed. I think in a way he was happy that Hitler took care of his "Jewish Problem" when the Nazis occupied their part of the Soviet Union.
