I have Pluckrose and Lindsay's "Cynical Theories" book. Your post made me check the index for any reference to China. China is not in the index. And your note is the first I've heard that America's problem of cultural Marxism is coming out of China. My first instinct is to doubt that story, because China doesn't have this problem and they mock the "Baizuo"

What I think is more likely is that the US establishment has been drumming up anti-China sentiment in the US for decades in preparation for the eventual conflict of superpowers that the establishment has been predicting.

You didn't say it, but I hear from many people that China is communist. Well they do use that word. The CPC is the Communist Party of China (not CCP btw, that is an American "we name you, you don't name yourselves" assholeism). But China doesn't exhibit ANY of the characteristics of communism. No common owneship of production, distribution or exchange. No allocation based on need. They have and honor private property, they have money, "to get rich is glorious" and they have in their constitution that "the defining feature of socialism with Chinese characteristics IS the leadership of the Chinese Communist Party" which is to say that as long as the CCP is in charge, they get to call it socialism despite what it actually is... that the CCP being in charge is the DEFINING characteristic and whatever they do defines what socialism is. It isn't actually socialism.

They are an authoritarian dictatorship, no doubt, but that can be very good or very bad, just like monarchy, depending on what the leaders do.
