Do you want the whole list? (half kidding)
Seriously. I have no problem at all with knocking the pegs out from under wingnuts, ego maniacs, demagogues, pandering populists, rabble rousers, intellectually dishonest pundits, etc.
Just because there's a shameless double standard which often protects extremists and nuts on the left from marginalization and public rebuke (the anachronistic but still effective "red baiting" taboo) doesn't mean that we shouldn't police our own ranks and demand higher standards of those that deserve our support as conservatives.
I happen to believe that one of the reasons conservatism has thrived is because we've done this in the past. I don't think it's a coincidence, for instance, that the conservative movement started to take off in the late 60's after Bill Buckley, Barry Goldwater and others decided to disassociate themselves from and marginalize the previously influential John Bircher wingnuts.
No, I don't think Coulter is anywhere near as extreme as the Birchers, but she is rude, unconvincing to anyone not already convinced, intellectually dishonest and often false or slovenly in her research. At best she's serviceable as a kind of rodeo clown (irritating leftists and making them charge in the wrong direction).
Great post, Stultis!
