What's wrong with calling them Teahadists? Both groups hate America and have worked tirelessly to bring Her to Her knees, they only use different tactics.
"Bring her to her knees"
How can a small group of people bring all the other people down? Have these small groups of people brainwashed and weakened the rest of the people? If so, then it might make more sense. We're blowing everything out of proportion. Humanity as a whole is on a slow but continuous downhill spiral. These groups, whether they are the Nazis, Tea Partiers, Democrats, whatever - they are a tiny problem. Humanity as a whole is falling so that's what we should be worried about it. But then again, we form this humanity.
We tend to think in groups - tea party, Democrats, Republicans, right wingers, left wingers. Why do we have to belong to a group? Are we so scared to stand alone?
And America is only as "good" as its people. It's not some creature standing on its own.
