We've banned this account for using HN primarily for nationalistic battle. That's not allowed here [1]. It's not what this site is for, and it destroys what it is for. Also, single-purpose accounts are not allowed here generally, because they aren't compatible with the value of curiosity that's supposed to animate this place (see https://news.ycombinator.com/newsguidelines.html).
If you don't want to be banned, you're welcome to email hn@ycombinator.com and give us reason to believe that you'll follow the rules in the future. They're here: https://news.ycombinator.com/newsguidelines.html.
Also, US isn't the only democracy in the world (it's actually a representative republic, but anyways).
