I was raised Catholic, but as time went on and left it, I think one of the misconceptions people who are still deeply religious have is that atheists or non-religious people are continually thinking about NOT having religion as much as religious people think about their religion, but the fact of the matter is, sometimes MONTHS go by where I don’t have a single thought about religion, the afterlife, God… When you grow up in an organized religion you tend to feel the lack of religion is some kind of continual rejection of it, and it’s hard to imagine people for whom it just isn’t a presence in ANY sense. When you realize the presence of religion is neither necessary or sufficient for any part of life, you can start to see how life satisfaction or lack thereof has nothing to do with belief. There are horribly depressed devout worshipers and annoyingly peppy and positive atheists. It’s an entirely different axis.
