I've been struggling with a better term for lower-case-c christians for a while now. I decided to use the term, cliche-christians, after reading an article promoted by Mark Sandlin's blog, The God Article.
The article that inspired me to use the term, cliche-christians, is part one, 10 Cliches Christians Should Avoid, of a three-part series written by Christian Piatt for The Huffington Post.
Both Mark Sandlin and Christian Piatt deserve major love (and karma points!) for trying to show people the Light that shines through Darkness.
