I'm not in any position to take it away from anyone, what's happening across modern societies is a realisation that the thing they believed in was a fantasy. It's an inevitable consequence of the advancement of actual knowledge. It's simply growing up and learning how to live an independent life.
Something like that happened to me when I was fifteen and atheist friends persuaded me out of my not-very-strong Christian upbringing. So I considered it grown up to live without such things and considered myself an atheist for the next thirty years. Then when I came to REALLY believe it was because I knew it was true, not because I felt any need for it.
