Propaganda buddy.I've heard that mentioned before. The Soviet Union wasn't really Marxist and just happened to murder 20million or so of its own people, same as China wasn't really Communist yet Mao managed to kill around 60million and Cambodia didn't really do Communism properly and murdered anyone with glasses. Anywhere between 80,000,000 and 100,000,000 people have died as a direct result of Communism and let us not forget they are still trying to do their best with it in North Korea so maybe they will get it "right".
Nobody seems at all bothered that Marx was a complete and utter racist, the sort of thinking that in today's cancel culture would see him sidelined to the Gulag or at least Talk TV.
All those dead yet still manage massive populations turning in super powers
Next you'll be telling me your African grandfather liberated Auschwitz
