Simply put, you were a troll.
If you bothered to read the FAQ you would have known how you were going to be received:
Note to Prospective Liberal Trolls: TPN does not tolerate liberal trolls. If your sole purpose is to join this site in order to disrupt the flow of constructive dialogue against liberalism, you will find your time here very short. You can and will be banned for being a liberal. If you wish to debate the virtues of liberalism (as though there were such a thing), there are many other sites on the web who will tolerate you. TPN is not one of those sites.
Tea Party Nation reserves the right to ban anyone for any reason we feel necessary to ensure the well being of the site and our members.
I've posted there three times all of which were critcal. I was briefly engaged with polite disagreement on two out of the three post.
"Brownshirts"? C'mon Robert, you knew what the site was about. You got what you had coming.
