Worse, you've been repeatedly posting nationalistic flamewar comments in recent weeks. This is bad. I understand the frustrations, but this is no way to make your case.
There's a greater burden on commenters who are representing a minority view, especially when the topic is divisive. That's arguably unfair, but it doesn't make it ok to break the rules, and it's not in your interest to do that.
