While this site trends heavily towards tech, it is not so narrow-minded that we cannot discuss things not strictly related to that subject.
The moderation question is always: what serves intellectual curiosity? https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que.... Once a topic becomes repeated enough, there's a power-law-style dropoff in how interesting it is (https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu...), except to people who have a strong identification with one side of an argument, and that sort of interest isn't intellectual curiosity, it's loyalty to a cause. That may be an admirable quality in many ways, but it's not a good fit for this site.
Nationalistic flamewar, which is the theme you're referring to, definitely falls in this category. That doesn't mean that "anti ccp" stories don't get attention here—they certainly do. Just not enough to satisfy the warriors, and rightly so, since warriors want every story that serves their cause to be on HN's front page.

Edit: it looks like we've had a similar conversation before: https://news.ycombinator.com/item?id=22870427, which makes me think that your "for some reason" is an insinuation of the sort the site guidelines specifically ask people not to post: https://news.ycombinator.com/newsguidelines.html. Please don't do that here.
i am not really sure how you make that determination, i personally find accounts of what the ccp does to exploit its citizens intellectually interesting when it is not widely reported
so, given you exponential drop off comment, i assume that means a small number of highly voted protest posts are allowed, and then past that point they will get modded. is that correct?
and yes, we had this discussion before, and i became confused in this context since protest topics also seem prone to intellectually uninteresting flamewars hn wishes to avoid
it seems there is an exception in this kind of case where a controversial topic is allowed if it is new
technically, police brutality and protesta are not new topics, but i suppose this exception is the current national impact?
