Why Do We Treat Das Kapital and The Communist Manifesto any differently than we

Why Do We Treat Das Kapital and The Communist Manifesto any differently than we treat Mein Kampf? I mean, communism did far more damage to the world than the Nazis ever dreamed of. Yet nobody talks about banning those books? I’ve read them all and if you know a little economics there isn’t much to either of them. One is a sentimental journey, the other is pseudoscience.
