For the past few days I've seen this quote on the TA homepage:
"When you understand why you dismiss all the other possible gods, you will understand why I dismiss yours" - Stephen Roberts
Well, I have a problem with this quote. Specifically, it's not true. Perhaps theists could say this to each other but it does not make sense for an atheist to say this to a theist. It's the same mistake made by somewhat cliche phrase - "monotheists disbelieve in countless deities; atheists just believe in one less."
It's just not that easy. There is a drastic metaphysical difference between a naturalistic universe and a theistic one. Atheists should not be surprised that statements like the ones I've quoted here are totally ineffectual. In fact, I suspect many theists may wonder of atheists who say these things whether or not they've understood the metaphysical and ontological implications of their worldview.
