Well believe it or not, communists and anarchists are a fairly small minority of the group that would be “the left” if you call the other guys “the right.”
I expect it’s more than two people I could hear from…🙄
Anyway this post sort of answered the question. The violent talk is coming from socialists, communists, and anarchists here on Lemmy, which have a very unified voice and shout down opposition.
Although I’m sure if they had anything they had to actually run (like a country) they’d be an absolute horror show of fighting, arguing, and bloodbathing each other until they got to the point where the strongest survived and could impose their vision of utopia on the masses.
