These narratives have real world consequences. Anytime you mention Xinjiang or that China is committing a "genocide" to liberals and conservatives it helps spread this shit. It helps reinforce Sinophobic narratives and will result in more deaths. Combat these lies and this propaganda where you see It. It is our moral duty to do so.
I mean, I think there's a distinction between saying "these allegations are unproven" and "there is substantial evidence, but we will defend them anyway".
