I'd love to be able to add a third axis to the classic left-right/authoritarian-libertarian political compass:
Dogmatism.
I feel every bit as removed from highly dogmatic people as I do from highly authoritarian people. I don't trust people who think that their choice of cause is more important, morally speaking, than the way they pursue it.
(Let's put it this way: while I'm not especially fond of right-wing authoritarian J.R.R. Tolkien, I'd rather hang out with him than, I dunno, Valerie Solanas or Cinque Mtume any day...)
(On the other hand, I had to pick Tolkien because it took a HELL of a long time to come up with anything approximating right-wing authoritarian who [a] wasn't necessarily that puritanically dogmatic and [b] I didn't instantly want to stab in the face with a dinner fork. The point's not so much that I'm fond of any right-wingers, so much as I *also* dislike a whole lot of dogmatic leftists. :) )
(Or Avon from Blake's 7, who is my favorite kind of villain, my favorite kind of anti-hero, and my least favorite kind of real-world company...)
(In fact, maybe a better example of a right-wing authoritarian who was on the "flexible/eristic" side of the Dogma axis would be Prince Machiavelli. And oh my god, my opinions about that guy are complicated and would not fit into 5000, let alone 500 characters...)
