Well… There was this thing called Soviet Union. They decided to try to speed up the transition to communism by using repression and violence. And ended up being a totalitarian state, a direct opposite of what a communist state is supposed to be like.
Of course you can argue that Soviet Union was not communist, it was just a state that had chosen to call itself communist for propaganda reasons… But still, Soviet Union is an example of a communist country that was unsuccessful as a communist project already by itself. Then came outsiders and helped make it even worse, but bad doesn’t become good by some people wanting it to be even worse. Burma is another example. I’d say they hacked away their own leg before anyone else, such as CIA, had time to interfere in their business.
Have you never heard of bolševiks and menševiks? What you’re explaining is what menševiks wanted, but what happened was what bolševiks aimed for.
And that was inhumane horror.
