I would also argue that by allowing users to resort to US whataboutism then these comments break multiple rules by introducing flamewars and engaging in political battles.. which, in my opinion, result in you failing to prevent (a) mind-numbing repetition, and (b) earth-scorching flamewars.
I’m also very curious about the logic behind down-weighting this thread: https://news.ycombinator.com/item?id=20336543. In my opinion, it’s very high quality journalism, with two journalists risking their lives to give unprecedented access to a region that’s been technologically cut off from the rest of the world. I also believe it’s the first time we saw what China did to the children of the families that had been sent to the camps.
