The difference is that by late 1980s there were few true believers. Those who held the power and dictated the indoctrination standards were mostly tired pragmaticists who were in power to be in power and little else. There were some people brainwashed enough to believe in theory of Communism, but (unlike in the early 1950s, when Communism intrigued a lot of young intellectuals), they were mostly the stupid ones.
It is horribly fascinating for me to see this replayed in America of all places, but with a distributed, socially enforced political policing instead of a powerful secret police like StB and Stasi. Some people seem to have a powerful authoritarian impulse in them. And obviously they have found a way to crush dissent even without a large governmental oppressive apparatus.
The trouble is that things have changed. If you dissented in Communism or doubted its value, the Western world was an obvious, freer and richer alternative. Where will current and future American dissenters find an alternative to a toxic feed of critical race theory being elevated to a state creed?
The main opposing power is (shudder) China. This really feels like a choice between Sauron and Saruman. I am not sure if Europe can escape from the roof of Isengard, like Gandalf once did. At least plenty of us see the reality for what it is - an ugly attempt to build a racialized dystopia on a base of post-BLM moral panic.
Edit: now sitting at -2 without even an attempt at a rebuttal.
