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 have mentioned my gender on a few other occasions, since I discovered that this community treats men and women the same way. I originally wanted to keep it secret because of how it would impact the way people saw my comments in gender-related discussions, but when I noticed it had no impact, and that a lot of LWers wanted to see more women posting, I went public for the statistics.
