Latin American Communists are NOT atheists. Most Latin American Communists are Catholics. Communism derives its support from Catholics. For example, Michael Moore is not an atheist but a Catholic. Nothing surprising here.
-—Communism derives its support from Catholics——
Are you talking about Catholic people, or the Church?
I assume you mean the former. Yes, many people in South America who identify themselves as Catholic, are communists. This shouldn’t be surprising, since 80-90% of South Americans are Catholic.
But communism is essentially atheistic, so a true Catholic can’t be a communist. Just ask the Catholics of China or Eastern Europe.
