Please don't take HN threads directly into nationalistic/religious/racial flamewar hell. That's exactly the opposite of what this site is for—regardless of how difficult the topic is. A topic being difficult just not justify setting it immediately on fire.
I've addressed that in numerous comments in this thread, for example this one: https://news.ycombinator.com/item?id=27646204. If you look at the past explanations linked from there, you should find that they cover it. If not, let me know and I'll try to answer.
The short version is (1) some stories are on topic for HN even though they have political overlap; (2) users still need to follow the site guidelines in such threads—in fact more so ("Comments should get more thoughtful and substantive, not less, as a topic gets more divisive."); and (3) that very much includes not going into flamewar, let alone repeating flamewar tropes.
