I see the term atheist as a person who believes in one LESS god than everyone else.
Think about the millions of gods, and thousands of religions ever dreamt up. A given group of people will reject all the millions of previous or subsequent gods for their god of choice, thus essentially renouncing 99.9% of all of the worlds religious views in favour of one religion for one reason or another.
I mean, take Europe ALONE for a second and consider all the deities that are still widely believed in. Obviously you have the big 5 religions, Christianity, Islam, etc, and the following sub-religions, like Church of England, Scientology whatever. But you also have hundreds of varied Baltic, Celtic, Irish, Etruscan, Finnic, Germanic, Ango-Saxon, Norse, Greek, Hungarian, Roman, Lusitani, Paleo-Balkanic, Sami and Slavic deities that don't even get a mention outside their own country. Each one of the categories I've just mentioned have AT LEAST 10 gods to their name. And that's just fucking Europe! Take Asia for example, thousands upon thousands of deities are still widely believed in! And India!... Fucking India...
Atheism is just renouncing that final 0.01%. Atheist means non-theist. Which means we don't believe in a god. In fact, it doesn't EVEN constitute that we have to believe in the scientific method, although it's usually used as a by-word for that, but whatever. That's not what atheist means.
Atheist is someone who doesn't believe a magical zombie being in the sky that created everything we see on a whim, and then gave humanity the go-ahead to take over so he can watch us fuck up royally, stumble around in periods of dark ages, ignorance, and hatred and only give us extremely subtle and often insanity driving hints on what to do next with our lives.
I'm just saying, if by some freak turn of events a god turns out to be real, he is a freaking asshole. And I'm jumping on the ancient Greek bandwagon and going to war the very second I see proof of that shit. He needs to be freaking slaughtered. And I will be there, in amongst the legions of billions of people that are pissed off with his shit, purging his draconian regime from the history books, and bringing peace and happiness to the world for future generations to come.
