The people who are best qualified to speak on these issues are those--the Uyghur, Kazakh, Hui, and even occasional Han--who have been victims of the camps and abuse faced therein. Going forward, my response to denialism will be to highlight one example of such testimony: https://twitter.com/TheDailyMao/status/1300685970900021249

Rest assured, I can do this for a long time. As a very sobering hobby, if you will, I keep track of testimony I find compelling for my own reference, and for use when speaking with (good-faith) denialists.

First up: Gulsimqan Bazarbek, an elderly Kazakh woman detained for holding dual citizenship. Her Kazakh testimony is on YouTube: Page 86 of the http://shahit.biz  Xinjiang Primary Victims Evidence Report summarizes her testimony in English.
