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.
To add to this:
Top US Army Chief Admits Xinjiang Uyghur Unrest is a CIA Narrative
NED (basically a CIA offshoot) admits to funding Uyghur separatist groups in a still undeleted tweet
Furthermore, some discussions accept that there's no actual genocide but claim that there is "cultural genocide". These range from:
citing demolition of mosques, which doesn't seem to be happening + IIRC China has the 2nd most mosques per capita in the world (behind only Saudi Arabia)
Claiming that Uyghur language is banned and they aren't allowed to use it in the 'camps' (yet even in propagandistic BBC documentaries you can see Uyghur script everywhere)
Claiming that they aren't allowed to wear "traditional dress" and "long beards are banned" - the beards part is actually true, but it isn't Uyghur custom to wear the "dress" they speak of or long beards - those are associated with the Uyghur separatists that were radicalised by ISIS.
Anyway, Uyghur population is growing, Xinjiang is thriving, Uyghur public figures seem to be doing pretty well for themselves. All very not-genocidey things. Are re-education camps the ideal solution? Probably not, but here we are living in the real world and not a utopia.
