for most of human history communism was being suggested by christians. you forget the history of the world before the industrial revolution. Utopia, was a book that was written by a monk and advocated for communism, it was also heavily christian. Before the ussr, there was new harmony, a communism commune that was founded by christians. Trotskyites are a great example of christian communists. communism isnt complex, and it isnt counter intuitive, and it isnt new, it;s a very ancient idea that has existed long before marx, and most communists throughout history were christians.
