Earlier quoted context omitted.
I reject the accusation of "whataboutism". Let's take those in order. "Why have I made 5~6 comments in the thread?" It's an interesting topic that I've spent over 5 years researching. "Why are you talking about the United States in a China thread?" I think this comment captures it well: https://news.ycombinator.com/item?id=19185364
Well I'm gonna be one of the people downvoting all the whataboutism I see, if you have 13 comments doing it that's 13 downvotes. Immorality in one region isn't excused by immorality in another. If what you mean to say is "This is absolutely inexcusable in China, and inexcusable in the West too" that's fine, but completely irrelevant to the article at hand, but I don't think that's what you're saying.
One can't fully comprehend an issue without comparing/contrasting it with other scenarios that may be somewhat comparable.
