It is completely off-topic.†
People will want meat to dig into for a meta-argument about global politics and I'm not going to offer it up, but let it just be said: it's very bad for HN that this stuff is being covered so prominently on the site. It absolutely, positively a slippery slope.
The site is clearly tacking away from serving entrepreneurial hackers and towards serving smart people who want a place to talk about everything they care deeply about.
I'm not writing my goodbye note or anything, but I'm having more and more of my best conversations in private cliques and off HN because HN is becoming less and less hospitable to those kinds of conversations.
