The bickering you often see online about whether it’s “genocide” is sometimes from a bad faith bombastic comparison to Nazi Germany usually rooted in misinformation
Also, the declarations of genocide are political. Based only on a few Uyghur women who travelled to UK, and who reported being sterile after having 4+ kids. Autonomous Uyghur/Xinxiang region has been exempt from China's one child policy, but there may have been sterility programs for excessive children.
Xinxiang prosperity has kept up/exceeded with China's provincial average since 2014. It's by far the most humane response to terrorism in human history.
