Yes I have heard Russians tell me to my face that Lenin was a Jew, and Stalin was so brutal, because he had no choice, he had to "purge the Jewish power in the Bolsheviks" etc. I also had a Russian tell me that Stalin went to war with Hitler due to Jewish interference in Russia, because they Jewish Bolsheviks were upset over Hitler's antisemitism and wanted to provoke a war (same with the UK, etc) LOL I think Russian kids think the monster under their bed is a 4 foot tall big hooked nose Jew with a nasty grin who wants to steal their candy money. haha
It's partly historical, and partly because Jews were (and are) heavily overrepresented in communist parties, especially in the early stages. This probably led to the view of Jew=communist murderer, causing a lot of resentment in Eastern Europe.
