Yeah, that was my initial reaction too. I've thought about it and I do like the idea of stealing the word "Bright" just as homosexuals have stolen the word "gay". Both are generally positive words that originally had nothing to do with the new meaning given to them. My current stance is that I'd

Daniel Dennett has proposed a similarly positive word for people with supernatural beliefs: "Supers"
