actually it's cynical & not reflective of the facts on the ground to compare Black America's plight with that of Uyghurs in Xinjiang. I would really say it's the exact opposite

Uyghurs have always had autonomy & legally recognized protected status & statehood in PRC, something Black Americans still yearn for in their country

Black Americans in certain poor & deindustrialized areas do not have any such prospects, whereas Uyghurs voluntarily join these vocational training centres & are given uplift and are integrated into the economy & society

Black people in many areas in the US actually face far worse demonstrable discrimination & violence by the state than any Uyghur
