They both believe their own bull****, but Tebow uses a kind of white, corporate approach to spreading the word, and Lewis opts for the ghetto preacher role. Both methods are insidious in their own way. Which is worse, I'm not sure. Lewis is much more "in your face", and has a pretty dark history, but Tebow (who I think is actually a pretty nice kid whose entire life has been engulfed by the church, and is easily manipulated) may be more dangerous, because he has some big money behind him.
