I find it amusing/insane that a government gets to decide what is and is not an allowed religion.
Q: Do you worship someone?
A: Yes.
Q: Good! Does he live in the clouds or in some Great Beyond?
A: No he lives in Palo Alto.
Q: Sorry, that's not allowed. We reject your religion on the ground of not being spooky/irrational/superstitious/ambiguous enough. Next please!
A: I believe in faeries!
Q: Too late. Plus that's not a serious religion. Faeries aren't real. Don't be silly.
