Now you're presuming to tell me what I should think about. Mags .. stop. You just don't know how utterly ridiculous you've become with your free-wheeling assumptions about what others think or should think about and how it all relates to what you're thinking.
An atheist need not concern himself with the least bit of science; they are free to be idiots and play with their own feces just like anyone else, if they are so inclined. They are just people, people bright enough to see what the religious are doing and they know it's not right for them. What distinguishes the atheists I know from the religious I know is they have a higher criteria for their beliefs. It's not that we don't want to be like you, it's that we, really can't be like you, not in good conscience.
As to your silly faith argument. I agree that all knowledge has a fiduciary component (your conviction comment). But that does not help your cause. The objects of our fiduciary commitments still admit to qualitative differences. You have faith in a shitty slew of narratives written by ignorant, impoverished humans whose knowledge of matters spiritual, for some reason, you wish to trust, but some of us have better things to trust in than the metaphysical graspings of our grossly ignorant ancestors.
