The argument does work in that context. It's the same across all topics as far as I know.
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.
