Thing is, John, there is a certain type of believer who can only see, bitterly, those not of their persuasion in a negative equivalent state to their positive belief. Equal and opposite. They are making two errors. First, as you articulate so well, atheists do not "not believe". Belief, at worst, is blind faith. A conviction based on no evidence, or, worse, which flies in the face of evidence. Belief in God qualifies on both counts. Of course, there is a meritorious kind of belief, which balances real evidence and comes down on one side more than the other. I believe that the Earth is around four billion years old. Most of the evidence I've seen supports that notion and there is little evidence against, though there are gaps in knowledge still to fill. I can rationally say that I believe the Earth is four billion years old, or thereabouts. I can't rationally say that God exists. I can rationally say that there is no evidence that gets anything like nearly over the bar that supports his existence. In fact, all the evidence I've ever seen for God isn't actually evidence at all. It doesn't pass the rationality test as evidence. There is always an impossible chasm to leap before it adds up to this, this, therefore this. Actually, we call it a leap of faith. Atheists don't care much for leaps of faith. We see a wonderful world out there capable of being explained in terms of the delicious commonplace, one that holds to the rules. Religious belief is a worldwide irritant that diverts intelligent people away from reality and continually threatens the peace. Douglas Adams said "Isn't it enough to see that a garden is beautiful without having to believe that there are fairies at the bottom of it too?" and I agree with him.

Their second error is that they forget that it's their belief that created us in the first place. Atheists are all their fault. We did nothing. We kept calm and carried on.
