They're parody religions (pastafarianism is, anyway). They're meant to be ridiculous, and they prove a point: we can't disprove their claims, but it would be asinine to say that FSM existed. I quite like these parody religions. They're amusing, and don't try to take over government policies.

I am a Proud Pastafarian. I worship the Flying Spaghetti Monster. I have been touched by His Noodly Appendage. On the 5th Sunday of each five month Sundays, me and other Pastarians meet at the Old Spaghetti Factory for pasta. The servers like us. We are cheerful, courteous and leave good tips. One server said that religious people often to not leave tips. They leave religious pamphlets instead. He said "You can't pay rent with pamphlets. They do not realized this."

The Pastafarians are just plain funny---I get their memes along with my news feed. It's a welcome change from the dreary political stuff that has been keeping me in a nearly constant state of anger and frustration.

I've never heard of adonitolgy before. I might just convert!

This actually brings up a good point about belief. I’m a Dudeist Priest, which allows me to perform ceremonies for money, but my belief is in Zen Taoism. The title is merely something to indicate a greater idea in a funny way. I could, more seriously, be a Humanist Priest (for example). The same is true of FSM because it seems obviously satirical to truly believe such a thing is serious.
I would say it’s not really the belief, or label, that matters but the veracity with which one asserts the label. At the point another’s belief threatens mine that tolerance stops. Dogmatic religions are a problem primarily because of their need to proselytize and convert than because of what they state.

The first one is silly fun...

The second one could be a fettesh... hmmm... people can get crazy sometimes...

I think they are a parody of religion which seems ridiculous to me. All hail The Flying Spaghetti Monster. May his noodleness be upon you. Ramen
