This is an incredible claim, given that nobody has even alleged that China is killing anyone in Xinjiang.

I recall when "genocide" used to mean "murder of a race" (as both the history of the term and its etymology make clear). It's now being devalued by obviously hyperbolic, rhetorical use.

I didn't consider it "genocide" when the US killed hundreds of thousands of Muslims in Iraq. If that's not genocide, there's no way it's genocide when China carries out political indoctrination in Xinjiang.
