I don't find your mocking of Christian musicians - who, whatever your opinion of their music, do what they do because of their love of Christ (they could just as easily hide their beliefs, after all) - very mature or Christ-like.
Maybe you just need to accept that people are not all the same, nor should they be.
I guess I better make sure this guy never hears my metal song "Jesus is way f***ing cool"...
I have seen what this Christian rock has done to crowd out congregational worship and flatter egos. I am most upset at undiscerning and weak pastors who opt for it over devotional, congregational praise and worship.
