I think for me it was the knowledge that my much beloved uncle, my mother's only brother, was an atheist. When I found that out my first reaction was "how ungrateful" (toward god). But he was really a great loving guy who would play a ton of sports with us whenever he traveled from the San Francisco area to where we lived in San Diego. I think that opened the door a crack.
Given that we'd stopped actually attending the Methodist church my father came out of before I attended school and the fact that my father was away at sea (in the navy) and unavailable to proselytize much of the time, it was actually quite easy for me to let go of religion.
