I would say this.  As Jordan Peterson has explained, the knowledge and true history of the Soviet regime under Joseph Stalin was suppressed in western schools.  Stalin WAS a VERY brutal dictator.  He had Gulag concentration camps for prisoners.  The conditions for these types of camps were appalling.  They were just as bad if not worse the camps of Adolph Hitler.  I would conclude that if this was at least taught today, a group like ANTIFA would not be so bold or brazen as they are right now.  These are my thoughts.  I will leave the link to the video right here.  https://youtu.be/XPfWThToClo
