I don’t know what those are - I just waded into Lemmy on a very large instance but I constantly see large numbers of people who proceed as if we’re all in agreement that capitalism is a proven evil and should definitely be put behind us in favor of a Marxist economy. This is what I consider extreme left. Now is it the uttermost tip of extreme? Surely not. But literal communism is not moderate left, or center left, it is far left. We could probably argue over the semantics of this for a long time.
