This is an extremely well-discussed and repetitive issue. If you want explanation about why this is not allowed and why your interpretation is inaccurate, take a look at these past comments:

If, after taking a look, you (or anyone) still have a question that's not answered there, I'd like to know what it is.
Many industrial espionage things done by china, and in late times by soviet Russia were entirely rational reactions to trade sanctions. They were illegal but not irrational. Simply declaiming "but its spying" or "but its trade war" isn't informative.
Sure there's quite a bit of anti-usa, but given what trump has done for America's reputation abroad, i don't think that has anything to do with being pro-china.
It's really polarizing: they appear to me as mindlessly spouting propaganda, and in the meanwhile they probably dismiss any critical comment, from me or others, as just coming from chinese wumao (which is amusing, since I don't have any ties to China, and my only tie to the US is via my employer... )
Frankly, my perspective is that the HN hive mind just downvotes anything that does not toes the US line (there are also upvotes obviously, but other topics don't elicit such knee jerk reactions).
It's really stifling discourse. I wouldn't mind it that much, if the current cold/trade war wouldn't have real world effects (and obviously, I hope it won't degenerate into a different kind of war)

I still think that the trend is there (in this thread, the comments aren't very nuanced and before I commented, the ratio of "against:non-against China" was 3:1, but now the ratio is much more even)
Without getting numbers for it, not much can be done to understand/address the situation
Sadly this makes it look like HN is soft-censoring China-related threads...If I were a mod (and if I'm not wrong) I'd be very curious of the downvoting patterns in these cases.
Unfortunately, when people encounter opposing views, they don't think of this simple explanation. Instead, they think nobody could possibly hold that opposing view in good faith, and therefore they must be an astroturfer, a shill, a Communist agent, a manipulator, a spy.
There is a great deal of previous discussion on this topic. If you want further explanation see these links:

If you take a look and still have a question that isn't answered there, let me know what it is.
But there are deeper reasons. I wrote about this the other day: https://news.ycombinator.com/item?id=24356496.
I think you addressed it well in the link you provided, especially with the SSM argument, but I have two soft suggestions for consideration:
1) I would personally like to see a HN rule implemented that requires you to post a reply to a comment before you can downvote or flag it. It's probably naive of me to think this would help stop brigading, but it seems like a logical extension of the current downvote setup.
2) I'd like to see equal treatment in terms of flagging both pro and anti- country/political platform comments. If politically charged posts are consistently turning into flame wars in the comments, which seems to be the case, the only way to address the issue without pissing off one set of people or another is to pretty much ban such comments in both directions. I know, easier said than done.
In any case, I think you're doing a great job and I appreciate how tough it is to moderate HN with the level of egos and strong opinions (mine included) on here. Thanks for keeping HN civil.

The idea of requiring a reply for downvotes or flags comes up a lot and I'm sorry to disappoint, but we're not going to do it, because all of our experience is that it would just lead to a lot of low-quality replies.
In terms of equal treatment of flagging: flags are almost all done by users and we can't control what they do, so this is beyond our power. When we do intervene, we definitely try to do it in an even handed way [1], so if you see an unfairly-unbalanced situation, emailing hn@ycombinator.com is also an option.

Im almost certain that all forums of any size are monitored and email notifications go out so the ideological warriors can go to work.
That basic fact easily explains nearly everything that you're seeing. People have opposing opinions because of their divergent backgrounds and experiences. On all sides, they feel extremely strongly about it, and so when they encounter each other online, they argue ferociously and draw extreme conclusions about each other.
