Peter Jennings is quoted in this Slate article...
Red-State PC: Why you can't call them "the Christian right."
...saying that our man-date delivering red state friends consider "Christian right" and "Conservative Christian" to be slurs (i.e., like "liberal").
Jennings phoned today and said, "It is not editorial policy" at World News Tonight to avoid the phrase "Christian right." He said that in covering religion for ABC News, he'd found that evangelicals "are offended" by the term "Christian right" because "it has become something of a slur."
We should work on keeping the slurs alive, and enhancing them.
