Good faith is integral to religious faith. Without it, you end up with people like Ted Haggard, Mullah Omar, or Pastafarians.
I think, however, Pastafarianism would be much more successful and useful as a religion if its adherents had even half a clue what they were talking about. Which is, in itself, much like the current atheistic upwelling in the Church of Dawkins. The most part of that movement is so focused on superficial bullshit that it's hard to take them seriously. It's like the old claim that atheists are better educated. Maybe on paper, but they still have to focus on the worst, least intellectual assertions of religion in order to feel better about themselves. Great, prove your intelligence by arguing against intellectual derelicts. Congratulations, Pastafarians. You are so smart, and deserving of so much respect. Hell, I don't know how I can ever match your contribution to society. Maybe if I had a wank and spooged on your cat. Or tried smoking celery stalks.
I won't tell you to not have your religion. But neither will I tell you I see any reason to give that sort of disingenuous, mean-spirited, intellectually flaccid proselytization any genuine respect.
