To me, this is neo-leninism in a nutshell.
A lot of neo-MLs seem to love to parrot old talking points of Leninist history like it's a matter of life or death as it was in the past, without really analyzing what were the material conditions back then.
I'm a crypto-ancom too and Soviet Russia or Maoist China aren't the ideal type of society I envision as "communism", but I reckon that Stalin was a committed Marxist who industrialized Russia at high-speed, did as much as he could to educate every Russian and make them secular polymaths, and reduce work hours as a whole, which is the kind of stuff Marx was envisioning when he talked about communism. Same with Hoxha, and his stance on woman's rights was based and he changed the old feudal culture of Albania forever.
Mao did the same things with The Great Leap Forward and the Cultural Revolution, even though it was disastrously disorganized, but for example, he intended with the Cultural Revolution to resolve what he saw as dialectical contradictions within China at the time, and I recently saw a Badiou lecture where we was saying it was a conflict between some students who wanted to form an static bureaucratic class within the party, and those who were freshly educated peasants and wanted to change things further, or something among those lines. There were basically two Red Guards, and the Red Guards allied with Deng won.
Even Khrushchev wasn't that revisionist to me because he still wanted to reduce work hours like Stalin, and hoped that Soviets would work 32-hours a week by 1968. For me, real revisionism starts with Brezhnev, Deng Xiaoping, the death of Tito and Hoxha. I would say revisionism won when the Sino-Soviet Treaty of Friendship, Alliance and Mutual Assistance ended, it was the death knell of the Leninist project. The Eastern bloc slowly succumbed to neoliberalism, who was booming back then.
Sorry to sound condescending, but neo-leninists should really try to expose themselves to a wider range of political theory (as much OG Marx & Engels as possible of course but also autonomists/communizers, contemporary anarchists, or even neoreactionaries like Moldbug and Peter Thiel to see what are their weaknesses) instead of repeating mantras from the time when neoliberalism didn't exist like nostalgic memesters. Neoliberalism is crumbling right now, what alternative do we have to offer that is compatible with the current material conditions?
