At least in my area of the US, knowledge of the CIA and US's crimes and whatnot is a lot more than it was a couple years ago. Nowadays, we have hot topics like Flock, data centers, and AI which all map very cleanly to (and are used to commit) said crimes. There's really no liberal conceptions that can't be eroded over time (assuming said person is, in fact, a proletarian). But that erosion has to be practical, you can't just bring up "Oh btw did you know the US used bioweapons on its own citizens without their consent multiple times?" or anything else like that just outta the blue, you have to actually connect it to lived experience. Bringing these things up out of nowhere will almost universally result in them just using the "bad apples" (it's just a few bad apples, we just need to get rid of them and everything will be good) defense. As Marx, Lenin, Mao, Vygotsky, and Luria demonstrated, THEORY MUST BE PRACTICAL. Theory without practice is a purely scholastic affair.

The same thing also goes with snarky rhetorical questions, random theory bombs, and thought terminating cliches like "That's just CIA propaganda!". These things are absolutely useless and are usually based in liberal egotism rather than any genuine attempt to educate. Even if they are genuine, no one is learning anything from you calling what they said CIA propaganda. This does not teach anyone why "CIA propaganda" is invalid, does not teach how the US Govt uses NGOs and the media to pursue its agenda, and is often deployed as a universal "stop all criticism" shield. If a teacher did not correct a student's mistake, but just obstinately called it "wrong" with no explanation, all it will lead to is frustration and resentment. If you are a Marxist in the West, you will have to live with the unfortunate and difficult reality that the vast majority of the working class are either liberals or "don't do politics", and work around that.

Ironically the Chinamaxxing craze is about as Western Chauvinist as it gets, and is a wonderful example of commodity fetishism. No one is celebrating the workers who actually did all of the labor to build China, they're celebrating abstract technology and making the same sort of banal racist tropes as usual. Yesterday, it was "OMG Bing chilling! Get it, Chinese sounds WEIRD!", today it's "I'm at a very Chinese time in my life!" (I consume Chinese commodities! Everyone laugh!).

It's literally the exact same grift as people in 2016 saying Japan was "living in 2030" because they had the Shinkansen, had "no crime and everyone is kind and respectful" and a bunch of 7/11s.

All idyllic illusions about China are best dispelled by actually investigating the material conditions of the country and its history rather than getting caught in PR fluff, and it's something that warrants extensive investigation both because China has become the new universal boogeyman of Western media, and because as conditions continue to deteriorate, people look to the more "advanced" countries in a vacuum for what ought to be done in their own, and because these people are liberals, they fetishize abstract technology and nominal socialism as in the Chinamaxxing trend. Always remember that Lenin's definition of imperialism was never limited to finance capital.
