this is definitely the most important thing happening.
It is really on the media outlets to actually provide evidence for their claims, but I know what you’re asking is to learn about the opposing left-wing view. I never have a good summary link on hand but I found this one: https://thecommunists.org/2019/12/31/news/blatant-hypocrisy-usa-lies-about-china-uighur-muslims/
Ultimately western propagandists can come up with new lies all the time that require reading to debunk, but you can usually tell how flimsy they are because they cite no real evidence other than western authorities, or rely on “research” from people like Adrian Zenz.
I love the fact you were so enthusiastically arguing about this without apparently knowing the first thing about it beyond sensationalist western headlines.
