I’m new to communism and when I read about Trotsky and Trotskyism I see there’s many heavy criticism about him like “being a Menshevik”, “Nazi collaborator”. I think, Trotsky’s works like “History of the Russian Revolution to Brest-Litovsk”, “The Permanent Revolution” are should to read to deepen knowledge of communism and its history. I’m not a Trotskyist or Stalinist just trying to learn.

Why Trotskyist parties are seeing as traitors or divise? Why his books are denounced in communist communities?
