i'd say it's a lot more likely it was killed because of the political slant. very few political articles are allowed to live around here, because they lead to divisive and unproductive arguments.
Stories about politics have a very high threshold to clear to be on HN, because there are many other places to discuss politics online, and few others to discuss the core HN topics.
I suppose reasonable minds can differ, but it doesn't delight my mind. I should be deeply interested in such an article, as an American who reads a foreign language (Chinese) and has lived abroad, but maybe precisely because I have that background I've seen better.
I gave that answer up-thread. I think people interpreted it as a political post. (Personally, I had nothing to do with flagging that thread. I didn't even notice it until it was dead and the metadiscussion began.)
