I don’t understand why such an innocent question can generate so much hostility, we’re all here to share and to learn.

Because OP and a few others have been repeating the same arguments over and over in this thread after many people argued a similar thing than I did. And also because it's a trend to try and dismiss the importance of "Marxism-Leninism" as a theoretical framework all over the world. It happened with Soviet and post-Soviet revisionists, and it happened recently in Brazil, where revisionists and toxic abusers of PCB were forcing people to dissociate from "Marxism-Leninism", adopting instead "Marxism and Leninism" in their documents. They are snakes like that.

I don't think OP is this kind of people. I think they are confused, but they insist on their confusion, and they push their confusion onto others. Then they repeat the same things over and over after several people have responded to them, and they continue to insist on it. I asked what's their point, what they are trying to accomplish, and they completely ignored it. I'm this close to consider they are in fact not confused, but they are dishonest, and they are not "here to share and to learn".
