Most, if not all Christian preachers take themselves extremely serious. This makes them preach from a very "convinced" point of view: they have / know the Truth
(mind the capital T!), and want other people to share it. FSM having "looser morals" and lots of humor, along with trying to keep religion out of science classes, doesn't have this capital T feeling. Pastafarians seek evidence, are attracted by science, and have a well developed sense of humour. Just try to imagine yourself preaching in the streets with that! Either you focus on the humour, and make it a stand up comedy show, either you try to explain people around what FSM is all about. I think you'll find FSM is more an Internet movement on one side, and a person-to-person thing on the other.
But, hey, I might be misunderestimating
(I just love
this word, and even more as it is the result of "accidental wit"!) the Pastafarians' creativity here!
