Under Leninism peasants are not proletarians. Let me underline that. Under Leninism anyone who worked on a farm was not a worker in the communist sense.
This is just a silly thing for you to say. "Proletarian" does not mean the same thing as "worker," it refers to someone who is reliant on selling their labor for wages. Peasants and proletarians are both workers, and it's a basic feature of the development of (e.g. European) capitalism that there were successive stages of owning and working classes.
I really don't think the butter-churn benchmark was representative of Leninist theory about divisions in the peasantry* (which is not me saying that they didn't make catastrophic errors). It feels to me like saying "People engaged in ritual cannibalism during the Cultural Revolution" as a way of characterizing the CR. Yes, such a thing did happen as far as I can tell, but it's not like it was a national issue or part of Mao's doctrine, it was a bizarre thing that took hold among certain factions in a certain region during a period of upheaval.
Obviously, Mao handled the peasant question much better, it's probably what he is given the most credit for, but he does something similar in his ""cosmology"" in terms of dividing the peasantry into three major types, (poor, middle, rich) and aligning himself fundamentally with the poor while accepting collaboration with the middle, making distinctions about "well-to-do middle peasants" and so on. Here's an example from Stalin. This is not to say Lenin and Stalin did not make grave errors, I repeat that they did, but when you were sneering about a ""cosmology,"" you were failing to explain these differences against Mao.
Lastly, I admit that Trotsky was more honest before his exile, but I really question using him as a source for criticizing Stalin when he would historically go on to do any anticommunist thing he had to in order to attack Stalin. I don't think you need to go and get, idk, some troubled journal entry from Molotov, your point is made, I just think speaking of Trotsky as though he's credible is, uh, fraught.
*Edit: I reread your post and it seems to be suggesting that the butter-churn thing actually came from Moscow. Is that so?
You were so much nicer to me before, but in my process of trying to look up that butterchurn thing, all I found was an argument that you had with Barx 12 days ago, where you had a tone much more like you have here. I'm not sure what I did to deserve it. Also I still want a source on the butterchurn thing.
I would consider farm labor in a modern state like the US to be proletarian. This should be obvious. It's a backward country in many ways, but the relations of production are not medieval.
Even if they [modern American rural workers] were peasants, or we were talking about an industrializing nation in the modern day that actually does have something like a medieval peasantry alongside a proletariat, I would advocate for solidarity among the working classes against the owning classes. Nothing I said contradicted that. You underestimate how specific a criticism I was making, just because I support one of Lenin's premises in a defective argument does not mean I support every premise, every inference, and every conclusion. You're shadowboxing.
It turns out you don't.
