You say this and yet, what videos? How many have you actually watched vs assumed were there vs read the headline? I've seen a bunch of photos and videos and all of them were either hoaxes (calling normal buildings camps), ridiculous misunderstandings (like saying the screeching of brakes was screaming victims), or gross misrepresentations (e.g. normal prison transfers being a slate of new genocide victims). But if you just skim through what just so happens to trend on Reddit, you'll see atrocity after atrocity and not stick around long enough to see the retraction, or the people in the comments debunking it, and so on.
There's a reason neoliberal outlets walked their claims back to "cultural genocide" over time, because there was nothing there except the testimony of like three people from a region of 15 million.
So that is one of the things worth considering, but that hypothesis isn't a get-out-of-jail-free card and needs to be weighed against other factors like the variety of sources and people involved, their history and material interests, etc.
Yes, I am saying things need to be scrutinized instead of just taken at face value if they comport with our prejudices, I apologize if that takes the wind out of your sails, but blind faith won't lead you to good conclusions.
