Hey another member of the "baptized at 8 years old because it was the cool thing to do and we didn't want to be left out club!" While I don't consider myself athiest today, I also don't consider myself Christian or religious.
The arrogance of religions in general is what finally did it for me. "We are right, everyone else is wrong," even though there are multiple religions who believe in the same God, and each of these are split into anywhere from 3 to dozens of denominations with different interpretations about supposedly the same God. None of them can know, and to claim to know is arrogance, not faith.
