Quote:An atheist is someone who is certain that God does not exist, someone who has compelling evidence against the existence of God
This contradicts what pretty much every atheist I have ever talked to mentioned about the burden of proof falling on the theist. To quote Hermione, "You can say anything exists if there's no proof that it doesn't."
Gay used to mean happy, now it means homosexual and is a slang term for retard. The definition of words change over time and one word can have multiple definitions. I don't understand why 'atheist' has to boil down to one concrete definition.
