If you're going to comment in this thread, please make sure you're up on the site guidlelines (https://news.ycombinator.com/newsguidelines.html) and note this one: "Comments should get more thoughtful and substantive, not less, as a topic gets more divisive." We don't want political or nationalistic flamewar here, and any substantive point can be made without it.
You repeat, above, that HN is not for nationalist flamewar, and requires substance. But this post is nationalist flamewar and isn't substantive. Allowing it while shutting down similar content from the opposite perspective is... unsettling.
Edit: Ok, I've read the first half and looked over the second half, and I think the moderation call was the correct one. Not saying this to pile on; I just wanted to report back.
b) You chose to override the will of this community who largely did read the article.
