I think the testimonies of rape are credible and major news organisations from multiple countries clearly think that leaked police files from Xinjiang are credible. I’m not aware of similar accusations regarding American prisons concerning black inmates.
Anyway, I expect you just won’t believe anything the BBC says (which I just linked to). I think the BBC are credible and reliable, but if you don’t think that, okay. I can’t change your mind of course. We will just have different views.


Interesting, I googled for reports of Arab emissaries going to Xinjiang and I found this from Time magazine, published in 2022:
Also you mention “multiple western* countries” as if western countries are automatically wrong. I don’t think that’s true. I think there are certainly biased media outlets in the West, but I think there are genuine and reliable media outlets too. I think the BBC is reliable. If someone proves their reporting to be plain wrong then I will re-evaluate them, but I haven’t yet seen that happen.
