In addition to what others have mentioned, I think if you ask for sources they’re basing their opinions on and point out objective problems with them and associate them with the US media’s atrocity propaganda track record, I don’t really see how it can be seen as anything other than being about media literacy rather than holocaust denial.

Some sources that I think should cover most of the problematic narratives surrounding the issue copied from my response in this thread https://hexbear.net/post/39756

Debunking stuff/illustrating the widespread problematic reporting surrounding this issue:

3. unreliable witness testimony - narrative changes from “did not personally see violence” and “there was no meat” https://www.theglobeandmail.com/amp/world/article-everyone-was-silent-endlessly-mute-former-chinese-re-education/ to “there were all kinds of tortures there” and “meat was served on Fridays, but it was pork” https://www.haaretz.com/amp/world-news/.premium.MAGAZINE-a-million-people-are-jailed-at-china-s-gulags-i-escaped-here-s-what-goes-on-inside-1.7994216

7. blatant propaganda witness testimony/Campaign for Uyghurs - “my friends and family are in concentration camps” from a Uyghur activist who worked at a CIA propaganda outlet and fucking Guantanamo Bay during the Bush administration https://www.reddit.com/r/IAmA/comments/e9ad4n/

What is (most likely) actually going on:

1. Not genocide - world bank investigation/statement: https://www.worldbank.org/en/news/statement/2019/11/11/world-bank-statement-on-review-of-project-in-xinjiang-china
2. BBC visitation with heavy editing and mistranslations - https://medium.com/@sunfeiyang/breaking-down-the-bbcs-visit-to-hotan-xinjiang-e284934a7aab
3. Unedited visitation to a camp and interviews with Uyghur students there - https://youtu.be/Jp5y9LCZqTA I made a post about it including parts that the translator had left out here https://hexbear.net/post/33959
4. All the Muslim countries side with China and even US-aligned Saudi Arabia sided with China since they had sent diplomats to visit Xinjiang and its re-education camps - https://www.economist.com/china/2019/07/27/chinese-actions-in-xinjiang-become-a-matter-of-international-dispute
