and it had a spotted history in the 60s, but it was hijacked by loons at the Dartmouth Review in the very early 80s. The Dartmouth Review, incidentally, was the breeding ground for such right wing slugs as Dinesh D'Souza and Laura Ingraham. It was one of the themes that they used over and over again and then, as they started to become national media figures, turned it into a catchword.

I hate the term and just won't use it.
