> Marx in special outlined a pretty well defined procedure to create what he called "socialism". Russia followed it to the letter
No, it didn't. I mean, the whole point of Leninism is “How do we skip past the requirement identified for Marx to have well-estsablished capitalism with proletarian class consciousness before proceeding to the socialist stage on the route to Communism?” Leninism abandons the essential context for which the Marxist program is designed. (And even then, the program wasn't particularly specific, unless you mean Marx and Engels program for the specific capitalist states of Europe in the mid-19th Century, which Russia was even more distant from then the generalized capitalist states of Marx’s theory.)
> It is dishonest to keep claiming "socialism" is something different than what you get when you follow the procedures to get there.
Marx is not the first or definitive socialist; socialism existed before and is broader than Marxist theories, so even if Russia and other Leninist states were an example of direct application of Marxist process, this would still be an example of mistaking a particular subset for the whole.
Judging Marxism by Leninist examples is like judging Christianity by Protestant Fundamentalism; judging socialism on the same basis is like judging Abrahamic monotheism by the Protestant Fundamentalism.
