That's an enormous leap to make, that the 'extreme right' is libertarianism. Says who? You? Your libertarian friends? That doesn't bear much weight when we consider that concepts such as authoritarianism, militarism, imperialism, 'rugged individualism'/social-Darwinism and social conservatism are very much right wing concepts employed by historical extreme right wing states... such as Nazi Germany, a widely recognised right wing movement. I personally haven't met any 'leftists' who fit the description of your penultimate paragraph. It's a cry lobbed by the right wing at us leftists though - we've been bombarded with allegations of racism on this forum for the past week or so about Cinco De Mayo bullshit. We're the ones being painted as racists, as extremists. On a broader level, I'd say it's even. The right wing lob just as many claims against the left, for example branding Obama a 'socialist'. The Tea Party movement seems to fit your definition rather well actually. As for your final point, and this actually on the topic of this thread - does this include moderately faithful Christians?
