I don't know this guy specifically, but it's been reported by other sources. This is a real thing that's happening.
I find the general Chinese apologism on this site strange. Even if it were 13k why would it not be an issue that China is placing people in concentration camps? Not even to get into the argument about the reliability of the 13k number because that's just laughable given literally every source that isn't China's government disagrees with that.
There is not "general Chinese apologism" on HN. What there is, is divisiveness on China-related topics that is growing for social, geopolitical, and media reasons completely beyond the scope of this site. Moreover, the population on HN is majority Western (50% US, 30% Europe, 7% Australia/Canada, if I remember correctly), so views here are skewed in rather the opposite direction to what you suggest.
HN users don't have to hold any particular views on these topics but they absolutely have to treat each other respectfully, including by not calling names (such as "Chinese apologism"), and nationalistic flamewar is not permitted.
Even if the population follows that distribution it doesn't mean the comments follow a homogonous reflection of the dominant opinion of the population.
I apologize if the apologism comment went too far. It is my perception in reading HN comments, and is not meant to be a normative view of the facts, and especially not meant to be nationalist comment.
You also did not add anything to the discussion by trying to call me out as "disrespectful." This just further derails the discussion. I don't know what the goal of your comment was, but to get the discussion back on track I'll just add more sources to bolster my position and let any substantive discussion follow:
I've been labelled as Chinese apologist, US spy, Russian troll, and Western separatists. How ironic is it?
