My apologies. Most modern Communists don’t view the USSR or PRC as examples of Communism. I falsely assumed you were in the same camp. Unfortunately for me, I can’t defend a Soviet Empire that caused the pain and suffering it did in Eastern Europe and Asia. Doing thing like killing half of all living Khazaks over a few years by intentionally starving them at scale, the Holodomor and the Great Leap Forward which killed more people than the Holocaust in less time are the sort of things I can’t defend.
The Communist system allows these genocides to happen in the name of Collectivism and hasn’t had a post incident process where it thinks and adds ways to avoid these problems for the next implementation is why I can no longer support Communism. When that changes I can reconsider.
