Sure.
I was an anarchist for a long time, gradually developed into an AnCom with more learning, and then eventually I sat down and genuinely engaged with what Lenin argued rather than just believing the received wisdom about why Lenin was a bogeyman.
My experiences with organising set me on the path towards becoming an ML long before I ever realised it and long before I actually read Lenin on his own terms.
I spent a long time in a sort of purgatory of radical politics, stuck in limbo where the way that I understood and conceptualised politics was crumbling away but I wasn't ready to admit it to myself that I was misled. It was actually really agonising to go through that. Sorta like being in a long-term relationship where you grow apart very gradually but you don't really notice it until there's an inciting incident and suddenly you review everything and you're like "Shit. This isn't working anymore. I don't know who you are, I don't even know who I am outside of this relationship, but I know that this relationship isn't gonna make it." I spent quite a while quizzing anarchists that I had contact with about certain things and this became apparent to me about matters of strategy and organising and broader stuff like economics and foreign policy and geopolitics. Deep down I was desperately hoping that my political realisation was actually just because of some fault in my own personal political development as an anarchist rather than it being about anarchism and that by talking it through with someone who was more knowledgeable than me it would rescue me from the political-existential crisis I was experiencing, that all I needed to do was to read more or adjust my perspective and it would all go away. Unfortunately this didn't pan out for me the way I wanted.
The next thing was, after realising that I was operating under false apprehensions in matters of politics, was to set about assessing history from a clear perspective to see if I felt that the narrative that I had adopted aligned with the objective facts and historical scholarship. This was difficult and it took a long time, and in some respects there are still things that I haven't arrived at a conclusion on because I need to do more reading but I'm okay about withholding judgment until I know enough to have a good understanding of things.
Unfortunately this is where it really fell apart for me. I learned more about anarchist movements and just the general history surrounding anarchist revolutions. In the two big historical examples of anarchism, there were strikingly authoritarian measures that were taken, and not by accident or by some quirk of history. I knew that anarchists would denounce these things if they had occurred under a different system with different leadership but I was interested to see how anarchists related to these things and responded to them. I saw a lot of denialism, reflexive dismissal (e.g. "that's just Bolshevik propaganda" when it was clearly not the case), and a surprising amount of excusing, deep skepticism, and that lack of curiosity that you get from people who genuinely don't care about a topic.
I honestly felt pretty betrayed, both by the very skewed narratives I was given about history and by a lack of principles or concern about authoritarianism within historical examples of anarchism.
In learning more about this stuff I also started seeing that over time the anarchist revolutions often tended to develop in a way that paralleled ML states due to facing essentially the same threats, the same contradictions, and the same material conditions. I stopped treating different revolutions as if it were team sports and I started to understand them on their own terms by developing a solid foundation of what was going on at the time and how they responded to their particular circumstances.
By this point I came to the conclusion that a revolution is never going to truly be complete as long as capitalism still exists, and as long as that's the case then there will necessarily be "authoritarian" measures needed to defend and deepen the revolution. In some respects I already knew this but it really crystallised in my mind because I spent time grappling with this idea. This in turn made me realise that I was much more aligned to the idea of a transitional phase of socialism than I thought. These days it's my honest opinion that if you really hash it out with principled anarchists most of them will agree that the day after the revolution you won't be able to achieve the anarchist end-goal but instead there will need to be a period of construction (and that's without even discussing the necessity of defending the revolution from internal and external threats). So my hot take is that one of the primary points of disagreement between anarchists and MLs is not about the necessity for a transitional stage but rather how long that transitional period will/should last.
Honestly with what I know and what I've been through, I feel like I'm sort of a corrosive influence on anarchists and I legitimately shy away from discussions of politics, history, and theory with anarchists (especially in real life) because I don't want to inflict the same sort of awful experience I went through on them and I don't have the capacity to provide an anarchist with much support in a sorta pastoral care fashion; I don't want to just smash someone's worldview and be like "Seeya later, nerd!" to leave them to pick up the pieces. In part this is because people can bounce to very weird places when their prior political beliefs implode and I don't want to see someone go from the radical left to an ugly political orientation, because then everyone loses, but also because I don't want to be responsible for someone going through a crisis that may really fuck up their relationships and their personal life. At worst, wrecking someone's deeply-held politics can push them over the edge and I really don't want to be the catalyst for that because I don't think I'd be able to live with myself if I knew that I had caused this.
