Most Maoists adopt anti-Marxist positions on a number of topics (e.g. rejecting all AES states) and are overall very dogmatic. I know this from my experience with them in the past.

I have never considered it that way. Although, to be fair, Stalin did comment on the need for each country to have their own revolution done by themselves without direct intervention from socialist states.

"You see, we Marxists believe that a revolution will also take place in other countries. But it will take place only when the revolutionaries in those countries think it possible, or necessary. The export of revolution is nonsense. Every country will make its own revolution if it wants to, and if it does not want to, there will be no revolution. For example, our country wanted to make a revolution and made it, and now we are building a new, classless society. But to assert that we want to make a revolution in other countries, to interfere in their lives, means saying what is untrue, and what we have never advocated." —Joseph Stalin, Interview Between J. Stalin and Roy Howard
