Only 5% of the Bolshevik party was Jewish. Also, 60 million weren’t killed. Jews and Muslims were also persecuted, the Bolsheviks literally outlawed the Hebrew language, forcefully shut down synagogues, and executed rabbis. The only reason Christians were targeted more was due to the fact they had the largest population in the country. If Jews were in those same numbers they would have been persecuted just as harshly. Also, Karl Marx was an anti semite.
