Antisemitism was frowned upon in soviet russia under stalin, and yet, at the same time, stalin went super hard on jews, several times. One of those episodes is known as "the great purge" https://en.wikipedia.org/wiki/Joseph_Stalin_and_antisemitism >>**The accusation that Joseph Stalin was antisemitic is much discussed by historians.** Although part of a movement that included Jews and rejected antisemitism, he privately displayed a contemptuous attitude toward Jews on various occasions that were witnessed by his contemporaries, and are documented by historical sources.[1] In 1939, he reversed Communist policy and began a cooperation with Nazi Germany that included the removal of high profile Jews from the Kremlin. As dictator of the Soviet Union, he promoted repressive policies that conspicuously impacted Jews shortly after World War II, especially during the anti-cosmopolitan campaign. At the time of his death, Stalin was planning an even larger campaign against Jews. According to his successor Nikita Khrushchev, Stalin was fomenting the doctors' plot as a pretext for further anti-Jewish repressions. See? "the accusation"... There isn't a clear consensus around the question when it comes to historians How comes? https://en.wikipedia.org/wiki/Joseph_Stalin_and_antisemitism#Great_Purge >>Although many of Great Purge victims were ethnic or religious Jews, they were not specifically targeted as an ethnic group during this campaign according to Mikhail Baitalsky,[10] Gennady Kostyrchenko,[11] David Priestland,[12] Jeffrey Veidlinger,[13] Roy Medvedev[14] and Edvard Radzinsky.[15] https://en.wikipedia.org/wiki/Joseph_Stalin_and_antisemitism#Doctors'_plot >>Similar purges against Jews were organised in the Eastern Bloc countries, such as with the Prague Trials. During this time, Soviet Jews were dubbed as persons of Jewish ethnicity. **A dean of Marxism–Leninism department at one of Soviet universities explained the policy to his students: "One of you asked if our current political campaign can be regarded as antisemitic. Comrade Stalin said: "We hate Nazi not because they are Germans, but because they brought enormous suffering to our land. Same can be said about the Jews."[52]** It has also been said that at the time of Stalin's death, "no Jew in Russia could feel safe."[53] **Throughout this time, the Soviet media avoided overt antisemitism and continued to report the punishment of officials for antisemitic behavior.[54]** "We hate Nazi not because they are Germans, but because they brought enormous suffering to our land. Same can be said about the Jews." See how that works? ... https://en.wikipedia.org/wiki/Joseph_Stalin_and_antisemitism#Associates_and_family >>To observe, as his daughter Svetlana has, that 'Stalin did not like Jews,' does not tell us much, since he 'did not like' any group: His hatreds and suspicions knew no limits; even party members from his native Georgia were not exempt. **Whether he hated Jews with a special intensity or quality is not clear."[64]** Tadaaaaa! The end, that's how the wiki entry on stalin and antisemitism ends Food for thought
