Chomsky whines about the USSR and calls its collapse "a win for the left". Absolutely unbelievable. Of course he has nothing to say about 1993 protests or the fact that the majority of Russians who experienced life in the USSR want it back.
Zizek calls China a "bad model for the left". Of course no actual socialist experiment is ever good enough for the ivory tower intellectual. Even worse, he keeps saying he hopes that China will liberalize its government. So fuck the DotP, lets just give away power to the capitalists, because that is literally what will happen in a liberal democracy, and he knows it.
China's capitalists are actively suppressed and controlled by the state. Reality is far more nuanced than you can imagine. Here's a good article to begin - https://thenextrecession.wordpress.com/2018/06/07/china-workshop-challenging-the-misconceptions/
Building socialism in one country is difficult, in a world where capitalist countries rapidly develop and build more and more technologies and methods to outcompete you militarily and economically. In my opinion, the CPC, while it has internal struggles between rightists and leftists, is still firmly on the path to communism.
You can do both. This seems to me more like you're uncomfortable talking about China.
