I'm still waiting for the incontestable proof China is trying to get rid of Uygurs. No, a known anti-China source such as Adrian Zenz being propped up by adversaries of China does not count. If you have the slightest understanding of discourse, you already know this: you don't get a biased source to report on the subject they're biased about.
It seems unreasonable to require that all bad information about China come from previously neutral sources. Is Zenz an anti-China source because he's "biased", or because he's reached a reasonable evidence-based conclusion that the Chinese government is very bad?
