Not gonna lie, being in good faith, the Chinese government having a 90% approval rate looks sus, at least to a Westerner. The West looks at this and shouts “That means they are brainwashed!” which I don’t buy into. Yet that idea that all these anti-imperialist people are just brainwashed really, well, brainwashes a lot of people. How can this be countered?
The good news is you can estimate what portion of the population actually believes the anticommunist propaganda. In the US, I don’t personally know a single person who believes “communism is evil” and didn’t vote for Trump. In 2016, Trump only had 63 million votes - which puts the max number of people in the US who believe communism is evil at 20% (the actual number is probably less since other groups voted for Trump too).
So tl;dr most Westerners who are fed anticommunity propaganda don’t believe it either
They do belive it. They just know the presence of anti communist propaganda is cynical and oversaturated. They don’t want anti communism to get in the way of having a comfortable life, but to say they “don’t believe it” is a big stretch I think.
