The Uighers do not have access to due process and a trial. I find that a glaring, obtuse omission in your argument besides doing whataboutism. It is a terrible situation in the US in regards to incarceration and our politicians (Bernie Sanders for example) openly, freely, fearlessly oppose it. I urge you to take a deeper look into China's state powers and complete lack of liberty, due process or law (yes, there are courts and written law in China but they do not appease the dissidents of the CCP's agenda).
What you're comparing is a regional regression of a particular demographic or culture. Imagine locking down 1.4 million people of Seattle metropolitan region because they worship no god and enjoy particular rituals, sending them all to re-education camps and then building HUGE projects to house them - all sponsored by the Federal government with strict orders from Washington, and the entire operation carried out by military and special police forces, setting up checkpoints in Seattle. Oh and I forgot that the threat is simply to sell your organs if you squeak and then kill you.
