EZLN did start out as a more authoritarian-influenced group (in the 80s, that was where USSR influence and support was going!) but they have since evolved away from that in major ways, especially after learning from/integrating with indigenous peoples after some initial contact with Mexican national forces. I am not as up on PKK/AANES history, but Ocalan's major works are primarily influenced by Murray Bookchin, who was extremely anti-authoritarian.

The soviets eventually came to be dominated by the Bolsheviks, who were majorly influenced by Lenin, but they were formed and initially populated by several factions. It's reductive to the point of absurdity to give Lenin the whole credit for the overthrow of capitalism in Russia (which was messy and complex), despite his outsized influence on the country from then on. Capitalism had only begun in Russia when serfdom was abolished in 1861 anyway, so the society that was overthrown was really one that failed during the transition.

Look, debate on these points in this thread is silly and I kinda regret being baited here. We need an easy intro to what socialism even is at this moment, for people like the OP, and we can talk strategy in another place. I'm glad we're broadly on the same team! Let's show others questioning society in this moment what we can offer.
