I never said the US was better than the USSR, I don’t really give a shit about the US. One shit country being slightly better than another one does not make it good.
I like how you characterised it as “some mistakes” . The whole famine business that ravaged the USSR was caused by sheer incompetence. A guy appointed by Stalin to manage agriculture came up with a fun idea of “communist crops won’t compete for resources” and forcing farmers to plant crops way too close. I’d say that was one of the greatest mistakes. There was also some killing the gays and some ethnic minorities but I think those were intentional.
I also don’t attribute anything to communism, only the USSR, communism hasn’t existed. I also attribute being the worst advertisement imaginable for communist to the USSR. They kinda ruined it for everyone else by calling themselves that.
