When a western leftist criticizes the camps, what goal are they achieving? Is it stregnthening the ideology, helping it realize that… there should not be camps? Is it showing who our real allies are? Is it proving a tendency wrong? No, I don’t think it is doing any of these. Then, all it is doing is helping the messages useful to imperialist states spread.

If you completely avoid any criticism whatsoever no matter how reasonable, and no matter how bad something said states may have done, you invalidate your opinion to a public that for the most part doesn't really understand the concept you are explaining and doesn't really care that much, plus you end up with lots of leftists ending up with a completely ass backwards judgement, the extreme example of this being the very weird antisocial online leftist who goes around shouting at people they deserve to be nuked and awaits for Xi to liberate them.

I understand the point you are making but there has to be a balance.
