Agreed. Many people identify Communism with Stalinism, Stalinism with Marxism-Leninism, Marxism-Leninism with Marxism, Marxism with Marx & Engels, Marx & Engels with Marx, and finally Marx with Communism. All of these identifications are heavily suspect, and are considered as such by the relevant experts (whether philosophers, sociologists, historians or political scientists). Unfortunately, few people on either "side" take the time to look deeply into the movement(s) they support or rally against.
