Out of interest, I just tried this. "Uighur genocide" was the fifth auto-completed search result. In the "Top" tab, the first video was a (maybe Chinese) guy saying he never saw any discrimination against Uighurs and maybe Americans should ask about the Hawaiian cultural genocide. The video next to it was from (presumably) Uighur people saying that they were suffering cultural genocide and China was selling their organs. Below that was a snippet from Wikipedia saying that China had been committing cultural genocide against the Uighurs.

The prominence of the Chinese guy "denying" the cultural genocide was interesting - I wouldn't assume he's a plant (it's equally likely he's just a rabid nationalist) but the placement of the video does strike me as a little odd. It had 300 likes, but rates higher than the second video which had 5000 likes? Does smell a bit.

This is from Singapore, by the way. I assume geography makes a difference.
