No, you said Marxism-Leninism isn't Marxist. Marxism-Leninism is Marxist. All of Marxism in the modern day has historically evolved from the era of Marx, be it through accepting ideas, changing them, or rejecting them. There is no such thing as a Marxist that has no opinion on Lenin one way or the other, for example. The ideology "Leninism" is used to refer specifically to Lenin's advancements, "Marxism" to the ideology created by Marx and Engels, and "Marxism-Leninism" as the unified ideology created by Lenin and forged in practice.
You then make vague references to the Russian Civil War without actually contextualizing them. The Bolsheviks did not "lose fair elections," and fighting amongst the Soviets did coalesce around the Bolshevik line, as the Bolsheviks were supported by both the proletariat and peasantry. The fighting between the communists and anarchists wasn't some one-sided betrayal either, it was a civil war and some sections of the anarchists that did not join the Bolsheviks took up arms against the soviets.
Further still, the soviet state was not some "permanent fixture." Such an idea is inherently against Marxist understanding of dialectical materialism, as nothing in the world is permanent, as well as the economic basis for the withering of the state. The USSR was a socialist state gradually building towards communism.
As for "Marxist-Leninism," no, I mean Marxism-Leninism, as understood by Wikipedia, science direct, and Stalin when coining the term. You're very confident about this point despite being trivially proven wrong.
As for Merleau-Ponty, yes, Western Marxism is incredibly fringe in the global and historical context.
