The claim is often made (or at least it was when I was in the faith) that atheists are arrogant for not believing in a god because they are claiming that they have scoured all of existence and knowledge and can be sure that there is no god or gods to be found (let's ignore that many atheists don't actually make positive claims about any gods one way or the other).

If this is so, then just about every theist on the planet is equally arrogant for not believing in Santa or Thor or the Tooth Fairy. Gods are no more deserving of special treatment than any other fictional character.
