False Claims of Antisemitism
Despite right wingers and fascists spreading rumours of Judeo-Bolshevik conspiracy theories, some historians have made baseless claims that Stalin was an anti-semite. For refutation please see the below letter from Stalin.
In answer to your inquiry :
National and racial chauvinism is a vestige of the misanthropic customs characteristic of the period of cannibalism. Anti-semitism, as an extreme form of racial chauvinism, is the most dangerous vestige of cannibalism.
Anti-semitism is of advantage to the exploiters as a lightning conductor that deflects the blows aimed by the working people at capitalism. Anti-semitism is dangerous for the working people as being a false path that leads them off the right road and lands them in the jungle. Hence Communists, as consistent internationalists, cannot but be irreconcilable, sworn enemies of anti-semitism.
In the U.S.S.R. anti-semitism is punishable with the utmost severity of the law as a phenomenon deeply hostile to the Soviet system. Under U.S.S.R. law active anti-semites are liable to the death penalty.
