But then you have people who will look at market socialists, anarchists, or some other brand of leftism and call them secret fascists or something like that. It's my experience (and yours may differ) that MLs are eager to insist that theirs is the only way and dismiss the rest
What you're describing is the analysis of Marxism-Leninism on other socialist tendencies based off of the historical materialist end results of their respective ideologies. A very simple example of this would be is how Marxists would prod anarchists as being more idealist over materialist over the fact that the more idealist members of the anarchist faction advocate for the immediate and total abolishment of the penal system can't reconciliate the fact that anarchists reestablished the penal system during the Spanish Civil War on their turf due to the material conditions they faced forcing them to make that decision. There's a lot more to this discussion that's being left out with plenty of worthwhile perspectives from all Left factions on the civil war in regards to this and much more.
It's in this regard that marxists will ruthlessly critique all ideological threads and each other all in the name of finding the most materially realistic path to Socialism within their respective home countries - and historically, revolution is the only means to the goal of establishing the dictatorship of the proletariat and a scientific socialist society.
