From Engels to Lenin to Mao, all have expressed their sheer repulsion towards dogmatism. Mao has even written one text after another and spoken in multiple meetings about battling this problem in the party. He, along with other materialists, has made it clear that the Markets are a historical category that have existed since before capitalism. Capitalism =/= Commerce.
Then how is it some Marxists who claim to have read theory call China capitalist and label its supporters as ‘Dengists’? Socialists created the fastest growing economy ever observed in human history that lifted hundreds of millions of people out of absolute poverty. And now these dogmatists wanna give its credit to capitalism!?
Their entire prejudice is based on the misconception that Deng Xioping did not follow on Mao’s thoughts. Deng literally heeded Maoist ideas such as “Let a hundred flowers bloom, let a hundred schools of thought contend” and “The masses are the real heroes, while we ourselves are often childish and ignorant”. He built the productive forces for the Chinese people based on—not in spite of—the continuing influence of Mao Zedong’s ideology. Now Xi Jingping is continuing both of their legacies.
So people who make such non-materialist and often times liberal critique of the Chinese economy have either not read theory or did not develop any dialectical and historical materialism to understand the theory!
As Marxists and materialists, it is our responsibility to confront these reductionist elements in our movement and bring back the pendulum at its correct course when it swings too much to either sides; right-wing revisionism or left-wing dogmatism.
“No investigation, no right to speak.” - Mao Zedong


I have noticed a lot of this lately as well, I feel like many people are being radicalized but not everyone bothers to read and understand theory, and not everyone bothers to unlearn western propaganda, etc. I was anti China maybe a couple of years ago, before I was a socialist and back when I was a part of the compatible left.
I know many Maoists who are convinced that Dengism is a real thing and that everything China did after Mao was bad, without bothering to engage with a material analysis. But I don’t bother fighting them since my time is better spent learning more theory at this stage lol.
Literally like the Trots with their “Stalinism”.
