Well a lot of the rest of Lemmy have seen numerous examples of it which is why they keep getting defederated from instances. This being about communism is a red herring as the lemmy.ml is run by self-proclaimed communists.
Furthermore, I rarely ever see hexbear users actually discussing communism or any other economic system. Typically it’s just ad hominem remarks about “the west,” strawman arguments, concern trolling as if they’re innocent victims, and carrying water for the Chinese and Russian governments.
