longrifle, I apologize. I got a bit testy. I was referring to the "anyone I disagree with is a kook" part. I don't think anyone is using disagreement as the criterion for kook-dom. I don't think Manedwolf or HTG would call people kooks, just because of disagreement. That would be a pretty low way to argue. But as HTG said, some people are kooks, and sometimes it's OK to say so.
I wouldn't call Hillary Clinton a kook, she's just a politician with some very wrong policy positions. But I would call Michael Savage a kook, even though I agree with him on a lot of things. He's goes on frothing-at-the-mouth diatribes, demanding all the "shyster ACLU lawyers" be put in jail, and such. Then he takes the credit for all manner of things that he had very little to do with. So, he's right up there with Howard Dean and Al Gore. As opposed to people like Harry Reid and Nancy Pelosi. I don't think they're kooks, just severely wrong.
As for Lew Rockwell, I don't remember how he earned his kook credentials. I think he used to call himself a fascist and then a socialist and then some other things. He tends to be all over the map, with various conflicting conspiracy theories. And that's pretty kooky. But then it's been a while since I looked him up, so I could be mis-remembering.
