The fact that China has ruled over Xinjiang off-and-on for literally thousands of years and yet the vast majority of people there are Ughyrs and other Turks should be proof enough that China is not "Settling" it.
Do you ever feel like maybe you've been lied to whenever people dig into the Uigher genocide thing and literally EVERY single source eventually circles back to Adrian Zenz or literal State Department mouthpieces like Radio Free Asia?
Do you ever look at the constantly increasing Uigher population and the fact that they, like other ethnic minorities, were exempt from the One Child policy, and think "hmmm you know what that doesn't make sense if they're genociding them?" Because idk, that fact would give me pause before I go into a xenophobic fury like a good little drone.
The UN didn't find "nothing," they found a concerning set of laws and practices that didn't rise to the UN's (admittedly broad) definition of genocide. Fwiw, though, the US's treatment of black people also doesn't rise to the UN's standard of genocide, so it doesn't mean everything is squeaky clean over there.
