Is PSL even strictly "pro-China" tho? Of course they have critical support for them as a multi-polar force and are very opposed to escalating tensions with them since PSL is anti-war. But I would imagine that the party still has its criticisms of Dengism in a purely ideological sense.
We have criticisms of the height of the Dengist era's backsliding and corruption, but fundamentally the Dengist program has proven correct, and the Xi era has been a demonstrable commitment to the socialist project. There's no point in purely ideological critiques - we need a materialist analysis.
I forget what I read that convinced me of it initially but I don't think cornel west is a good faith actor at all. Wrecker/grifter shit all around, and I don't have much more faith in any of the people that promoted him
