So they are people who want to violently or otherwise enforce their ideal view of some flavor of communism on the rest of the world

Its more than that (supporting totalitarian genocidal dictatorships just because they oppose the west or are “communist”) but that is part of it too

And they try to realize this by organizing and radicalizing people on social media?

Apparently, yes lmao. They are the most twitter brained people alive. (i know ML parties exist irl, but i wouldn’t say they are all tankies)

They have the brain capacity of a child, unable to comprehend beyond “my side good, your side bad”
