It doesn’t matter how long you make them read Lenin and break rocks in the gulag, the second you let them out they’ll see an AI generated meme from a CIA holdout posting from a bunker somewhere and immediately revert to being a burgerbrained fash.
I think we need to just dump them on an island somewhere and put them under continuous naval blockade and internet blackout till they revert to a Hunter gather society.
I think the average Trump supporter is reachable—and if you have the resources of a government, as you seem to be imagining, I think they are reachable at scale. This is the 21st century, at this point the experts know how to influence people. Generations of marketers, academics, and psyops specialists have studied this problem. The knowledge is out there. If the CIA can spin up a color revolution, we can reeducate chuds.
But this all assumes a peacetime scenario where a communist government presides over a large population of chuds lol. Idk if that would happen in real life. Others can weigh in, I have no idea.
