Yes. You’re right. It’s pretty close, though, and “genocide” is handier than a drawn-out, nuanced description for which there isn’t a convenient term. Abusing the word “genocide” is little worse than using the extremely broad and easily downplayed “human rights abuses.” The latter is as equally appropriate to US police treatment of minorities as to China’s treatment of the Uyghurs, but you’d agree they’re vastly different in scale and scope, right?
