The comment was pretty darn civil, we've had political discussions all the time, and you know better than I do that not every well-received comment in HN sparks "intellectual curiosity".
Furthermore, for the life of me I don't see the "flamewar" that was started here. It seems more like you started the flames by threatening an immediate ban. So I'm a little shocked to see you reply like this. You could've just said the comment is off-topic and deleted it quietly, but to suddenly call it a nationalistic flamewar... I don't see how you expect people to take that.
