Actually yes, the point of Marxism Leninism is that it follows Scientific Socialism, so the vast majority of things are no longer an opinion but simply a bank of knowledge that's grown over time with hypothesis and proven results, so that some issues are resolved and we need not seriously discuss them as they won't change in this mode of society (bourgeois led).

Firstly, it is not true that fascism is only the fighting organisation of the bourgeoisie. Fascism is not only a military-technical category. Fascism is the bourgeoisie’s fighting organisation that relies on the active support of Social-Democracy. Social-Democracy is objectively the moderate wing of fascism. There is no ground for assuming that the fighting organisation of the bourgeoisie can achieve decisive successes in battles, or in governing the country, without the active support of Social-Democracy. There is just as little ground for thinking that Social-Democracy can achieve decisive successes in battles, or in governing the country, without the active support of the fighting organisation of the bourgeoisie. These organisations do not negate, but supplement each other. They are not antipodes, they are twins. Fascism is an informal political bloc of these two chief organisations; a bloc, which arose in the circumstances of the post-war crisis of imperialism, and which is intended for combating the proletarian revolution. The bourgeoisie cannot retain power without such a bloc.

~ 1924, nearly one hundred years ago in Concerning the International Situation

Historically this has been shown time and time again. SPD in Germany cooperating with the freikorps during the Spartacist Revolution. Italian Social Democrats cooperating with Mussolini. The failed unity against naziism of the socialists and social Democrats. Labour cooperating with the Anglo empire to liquidate those colonized, labour cooperating with the American empire to liquidate Iraqis, progressive elements in the US having dogshit foreign policy because it may lead to better outcomes here if they shut up (Bernie supporting Israel and bombing Yugoslavia to smithereens). Etc. We can simply look at the course of AOC's career and see the same things appear time and time again. Fascism isn't just Nazis, it's the entire apparatus the bourgeois state uses and will use to attempt to annihilate leftists when they present any challenge whatsoever. It's not wrong to apply these historical teachings to today's figures when the reasons for it happening haven't changed.

I also once would all read this and find it ridiculous, but frankly, the longer you spend organizing IRL and interacting with the state and other leftists, the clearer this all becomes. I've gone from an anarchist to a staunch ML because MLs are almost always correct and willing to correct themselves when they aren't (Cuba and LGBT). When I say AOC is a fascist, I know I won't convince those who haven't tried to organize IRL, but the real heads who know will know. And those who care about Palestinians being liquidated by the United States will come to this understanding as well.

Edit: the point is having a sound analysis for MLs so they can properly engage with and tear down the world's order. Figures like you can act as the milquetoast that gets others on board, whereas eventually when engaging with the reality of the world they will understand and appreciate our seemingly extreme rhetoric.
