Have you ever convinced a religious person to become atheistic? How did you do this? How long did it take? Were the people in some sort of life crisis, or were they just living along?
This is probably a quite difficult task of persuasion. So stories how people were successful at it could be very interesting to improve ones' persuasion abilities.
Relatedly, it might be interesting to know what religious groups have gathered on techniques to convert people to their religion - are there some manuals/techniques floating around?
I'm sure this is true in some cases but not all of them. I've barely ever talked to anyone about my own fall from grace as a child and then again after a relapse in my teens, it was almost a completely introspective experience although what is interesting is that my relapse into Christianity was very much a social product. Still, atheism has never been an important part of my identity. In my mind the fact that I don't watch televised sporting contests sets me further apart from my peers than the fact that I'm an atheist.
I de-converted my wife just by being an atheist and never making a big deal about it one way or another; I think she just needed to see an example of someone getting along fine without the theism.
