Ed Babinski has just introduced me (via-e-mail) to a web comic called Which Circle, which is dedicated to making fun of Campus Crusade for Christ. The creators are ex-crusaders who, as far as I can tell, have remained Christians, though of a non-fundamentalist variety. It's a great find.
EDIT: Even though they have nice things to say about liberal Christians, there are points in the commentary where they refer to Christians in a distinctly third-person manner, indicating they don't consider themselves Christians anymore. So I'm not really sure about what I said in the original version of this post.
