Hacker News is not a site for engaging in political battle. Most politics are off-topic, but a blanket ban would deprive the community of topics that are indeed intellectually interesting, or representative of new phenomena. The political discussions that we do have, then, are for the community, and the expectation is that comments are thoughtful, patient, civil, and substantive.
Creating accounts that only post politically is not good community behavior, nor is reposting comments that have been flagged, nor is making deliberately inflammatory (troll) statements as you have. These behaviors are against the goals of this site and they just don't belong.
