I’m currently not in the position to have lengthy discussion about things without taking the theoretical basis of this place and the adjacent works (prolewiki) into account. So i’m sorry if what I say isnt easily understandable for you.

Here is the article about trotskyism which portrays it as exactly the menace that it is. I also suggested a book that gives a good overview of why trotsky and his ideas are anti marxist and sometimes completely fabricated.

I sadly cant find the stuff about china atm but suffice it to say that imo, “critique” on china is ever present in western countries. China is the butt of every news article, every day. Casual sinophobia is everywhere and opposing it is likely to get you chastized.

Even if someone is a marxist theorist (which is incredibly rare) and has insights into china (mostly through living there) that allow them to form an opinion worth listening to (which is a very small number, globally), the pure abundance of racism and “critique” basically forbids them to voice it out of pure antiimperialist supoort as one would just help the unhinged west further entrench their citizens. In a purely theorist setting, in a closed off room, i can see such stuff discussed but nowhere else.
