Oh, I literally just had a comment on my thoughts on it. Here is it pasted, since I don't want direct linking to it. TLDR it's probably majority those 14 year olds, not a false flag.

I don't think they are pretending to be those things. They truly believe themselves and their interpretation of Marxism, Marxism-Leninism, communism and socialist projects to be true and just.

The only issue is that they come from a specific strain of western leftist that got into the "uwu dank Soviet club" meme of the mid-10s and never evolved past that understanding of the people, projects, policies and states they stan like a fandom. They could take some lessons from the anarchists tbqh, but they'd rather post PPB and "liberals get the wall". Very annoying.
