I think one of the most surprising things about being a non-believer of a god is when talking to someone about it and finding out they don't believe either!
I don't know and don't dare to ask but I am 36, and while I was dragged kicking and screaming to church as a child, I rarely speak to other Gen X's that grew up the same. At least up here in good ol Spokane WA. My social circle is small but I'm more shocked when folks my age subscribe to religion. And even they admit that they rarely go to church.
Now, usually people prefer to claim "agnostic" as opposed to "atheist" but I'd still rather hear that then Episcopalian.
There are many small towns around here and our side of the state votes Republican. So, religion is still around us and tends to flair up in bars in lesser populated towns but other than the guy standing on our busiest traffic corner with the bull-horn and cross tied to his back, I don't encounter too many zealots around here. I could find them easily, of course, if I went searching like I could prob find a hooker or heroine but bigger cities offer all kinds of corners to hide in and I like mine. I'm generally safe to scream "I do not believe in God!" without fear. But I do not feel safe to be a woman. Ain't that some shit?
I about shit myself when I first met a neighborhood couple and one of the first things the husband told me was that they were atheists. It was the first time anyone had just blurted it out so comfortably. It seems to me like too many people are afraid to openly admit it.
Interesting the difference in countries, I live in New Zealand and have only ever had one very religious Christian friend. Maybe just where I was raised in a large city. All my other friends are just meh don't care, or Hindu, Buddhist or Muslim.
Same experience for me in NZ, religion is not a big issue. Saying you don't care about Rugby or Cricket scores is a trigger though
You never know. Harder out there-easier here.
