I think the Chinese government is totalitarian and aggressive, and the standard of due process and human rights is very different of what we consider acceptable in the "west".
I also wouldnt be surprised if things like widespread facial recognition and other types of intrusive vigilance is present (something very bad),I also would not be surprised if the area has received a large Han migration (something more gray, neutral). I also acknowledge that people that they may consider dangerous (number in the tens of thousands? are or have been detained for longer periods) and that the youth population receive education to become integrated to the Han majority.
Having said that,I have seen 0 actual evidence of genocide, beyond very wild speculations. 0 bodies, mass graves, executions,1-million people in jail etc. If I see the evidence I of course will change my mind.
On the other hand almost every notably speaker of the genocide have had an axis to grind against China. From the crazy newborn Christian Zenz, to the Uyghur woman who worked for the CIA and did a reddit AMA, to yes! people like Pompeo or Trump or even the mainstream western media.We are in the middle of a new cold-war.
Uighurs are exempt of the 2-child policy reserved to the Han, and their population have increased in the region compared to the previous decades.China has also be receptive to receive inspection and FWIW the entire muslim block is with China.You could argue that they are being blackmailed, but some of them are rich enough to not depend now or in the future from China.
Anyway, it is going to be interesting once the proposed French laws against Muslims extremism are in place to see if the same standard will be applied to the reporting. Interesting times these.
