Marxism-Leninism is Lenin’s advances on Marxism combined with Marxism itself. It’s an update, bringing Marxism forward in time to the era of imperialism. “Maoism” was a deviation because it contradicted Marxism and was dogmatic. We can discuss the differences if you like, but you seem stuck here.

For another thing, there’s literally everything that people like you ever say was “Stalin’s fault, not Lenin’s” when attempting to derail conversations away from “bad shit that happened under the USSR.”

Don’t put words in my mouth, make an explicit claim. What were Stalin’s innovations over Leninism? I have a hunch that you have no clue what “people like me” say. Everything I have said is easily verifiable, yet you seem allergic to backing your own claims. Why not read Stalin’s Foundations of Leninism, and point to what Stalin himself invented rather than took from Lenin. You seem to give Stalin far more credit than he gave himself!

Go ahead, pretend you’re bored and not way in over your head with someone that actually knows a decent bit about Marxism.
