For all the faults of the western world, we will have to serve as the preserver of the record of all these abuses in countries that don't allow anything but the official version to spread. It should be noted that without the international news of the Uyghur repression there wouldn't even be an official version from the Chinese government, they were silent about it until it became big. We can't do a lot for the Uyghur people, but at least let's not get fooled into doing Xi's work for him.
You read or heard about those things from reports originating in western media (yes, you might have read it somewhere else, but even the People's Daily is reliant on western media for the stories it makes about how the west is bad). The free dissemination of information sets us apart from the likes of China and Russia. We shouldn't self-censor news from China because Biden is an asshole, we can report about both. If the situation really was symmetrical, there wouldn't be any discussion about US abuses, because it would be outlawed.
