While it is true that Jew-hatred has long been a feature of Russian culture, the mistreatment, persecution, and prosecution of Jews inside the Soviet Union was not uniquely anti-Jewish to the exclusion of all other religious communities within the Communist States.
There is some truth to the Communist's claim of "social justice" and "equality"; provided you understand that all are to be treated equally and with equal justice under the Communist legal system.
Translated into plain English, that means that any and all religion was essentially forbidden by the state, for only the teachings of Marx/Lenin held ultimate truth for all. In addition, Communism declared all ethnicities and allegiances other than to Communism to be null & void. In their place, the Communists installed The New Soviet Man, the supreme Socialist Internationalist with no loyalties other than to Communism.
So...in the twisted neologisms of Marxist-Leninist theory, it is true that Jews were treated equally with every other Soviet citizen.
