Why is it then, then when you see an outspoken communist on the Internet they freely use Soviet symbolism like hammer and sickle. I take that as an affirmation of the fact that these people don't really think that Soviet Union was a bad implementation of communism. Like, there exist far-righters who avoid using swastika because they don't want to be associated with Nazi Germany. Why do most communists want to be associated with Soviet Union specifically by adopting its symbolism?
