I suppose that my perception of atheism is simply that it entails believing nothing of God, gods or any other spirituality bollocks. That isn't to say it's a flat denial either, as a rational person, it is also our position to appeal to rationality and truth in every case, not simply the one of god/s. Therefore, I perceive my atheism as simply refusing to believe the unbelievable.
Religion is an attempt to answer the philosophical questions of the unphilosophical man.
