You're not adding any information when you post like this. It's just a big opinion with a strong feeling attached. When someone else with the opposite opinion comes along and blasts their opposite strong feeling, is any information going to be exchanged? No it is not. Therefore it's off topic for thoughtful conversation, which is what we're trying for here.
HN threads thrive on curiosity and specifics, wither on the gruel of grandiosity, and burn under scorching rhetoric.
The problem with bringing such links into arguments like this is that no one does so for reasons of intellectual interest. For example, in this case, people aren't actually interested in the plight of the Uighurs. Rather, it's convenient ammunition for justifying pre-existing political and national feelings. Such a move is not part of thoughtful conversation at all; it's just ideology and tribal loyalty, which explains why the discussions are so utterly repetitive—and therefore off topic for HN.
I'm not sure what to say if HN's position is that it's too controversial (or is it that "all denunciations are the same"? They are not) to call out such actions. These discussions are clearly related to the topic at hand.
Maybe those of us criticizing the Chinese government aren't saying anything new, but that doesn't lessen the need to speak out. It's neither "rhetoric" nor "grandiosity" to point out that it's morally wrong for a government to act the way China's does.
I would expect the PRC to put a lid on this sort of criticism, not Hacker News. It's bordering on complicity.

What an awful sentiment. Please don't profess to know my own moral compass. I am deeply concerned and sickened; we all should be. These people are being forcibly relocated and tortured by their own government.
