To be fair, I don't think many communists globally are fans of Trotskyism, considering it's predominantly western and liberal-compatible. The vast majority of communists globally are Marxist-Leninists, Trotskyism is seen as more fringe. Trotskyists tend to already begin with anti-AES stances (for a variety of reasons, usually a combination of Red Scare propaganda mixed with alienation from capitalism), so going from "socialism is a good idea but never existed" to "socialism is a bad idea because what's existed hasn't worked" is a common jump. A former Trotskyist making loads of money off of denouncing communism is both entirely predictable and hardly compelling for those who've studied communism in theory and practice.

As for the rapist Eric Blair, also known as George Orwell, the western world listened to him too well. He didn't see through anything, rather, his position as a British fed (known for keeping a journal of people he knew and suspected of being Jewish and/or communists) and propagandist was extremely useful to western intelligence agencies. On Orwell is a good essay going over his dreadfall past and role in propagandizing. Orwell has been taught in countless schools not because of any truth, but because of his utility.

As for Figes, another that earns an enourmous sum of money from preaching the bible of anti-communism to serve capitalist interests, better historians exist. Syzmanski's Is the Red Flag Flying? The Political Economy of the Soviet Union today, Pat Sloan's Soviet Democracy, Human Rights in the Soviet Union, Anna Louise Strong's This Soviet World, Mary Stevenson Callcott's Russian Justice, the recently deceased Dr. Michael Parenti's Blackshirts and Reds, all the way up to Professor Roland Boer's Socialism in Power: On the History and Theory of Socialist Governance, there's tons of academic resources to get a much better view of socialism in practice.

I don't expect you to read these, of course, my point is that just like you don't expect to change your mind by me sharing evidence counter to your views, I'm unlikely to be swayed by professionals repeating standard anti-communist dogma. It takes a much greater amount of study and reflection to go against the dominant, hegemonic culture, nearly every common anti-communist talking point has been wielded against me at some point simply by me stating that I support socialism.

Is there anything specific you'd like to discuss, regarding the effectiveness of socialism/communism? We can have a constructive conversation surrounding specifics.
