Jews control Hollywood and all entertainment in the western world. The control narrative, so they will never allow anything to show them in a negative light. Communism is an invention of the the Jew, so to explore Stalin and Mao would be lead to exposing their evils. Even documentaries about WW2 and the Nazis never explain why they hated the Jews. They just make Hitler out to be the Devil, the Nazis evil and Jews an innocent undeserving victim. Like Hitler and the Nazis just decided one day to exterminate the Jews because of an irrational hatred that had nothing to do with their actions. It's exactly how they are now portraying Putin.
