T-shirts available online somewhere:

1) Militant Agnostic: I don't know and you don't either!
2) Militant Apatheist: I don't care about your silly god!
3) Militant Atheist: There's no goddamn god, goddamn it!

What I find dumb is the denial of reality to allow for your faith. If believers would accept reality, and believe that their god created the world to seem to have that reality, that would be fine. E.g. - the Earth is 6000 years old and Humans were created on the 6th day of creation and it was made to appear as if evolution and geology were true. That seems fine. The denial of evolution or deep time, though, is worse than ignorant.
