It is not “starting a flame war” to point out the masses of comments that rushed to draw racist and xenophobic conclusions about the killers identity before this information was revealed. If you as moderators of HN do not moderate such behaviour in the first place, then don’t be surprised to find that users might take it into their own hands.
You could have made that point without garish flamebait like "tech executives to be forcibly housed in a palace against their will". If you had done so instead, I would have had no reason to post a moderation reply.
We're not trying to combat anyone's substantive points. We're just trying to prevent garden-variety internet destructiveness. As you have a history of the latter, it would be good if you'd review the site guidelines and take them more to heart: https://news.ycombinator.com/newsguidelines.html.
