I'm fairly alone in this, and I say Ex-Christian to indicate I'm not Atheist but I don't know if that's true. Anyway, this is something I've been struggling with a lot. I just spent 3 hours last night talking to a Power salesman, because we had a good time chatting and I don't get that outside my friends and work. There is no forced place for me to talk to acquaintences.
Honestly, if I didn't disagree so strongly with the theology of the LDS (Mormon) church I'd go back to that. They are FANTASTIC for kids, parents, events, etc. They instill great morals (other than homophobia and some other things I disagree with). But they are in general very nice people.
So where do I go for a "third place" without God being involved, but I still get the, "hey man we missed you last week, where were you." and "Have you given your money to God lately?"
Sorry this struck a nerve, and I'm almost ready to go back to the LDS church just so Sam has people he knows but to try to counter the Theology by exposing him to other beliefs as well. IDK.
I think that if you bring your kids to church, they'll still look to you for what to believe (or not to believe!). Be straight with them, though. Tell them that you're just going there to have something to do. My parents pretty much said that and I didn't have any problem with it. Maybe ask them not to repeat that in front of others though.
I haven't been, so maybe I'm wrong about there being any kind of spiritual focus to the group, but I might describe my coworkers as an ex-Christian (who's fairly bitter about it) and...well, the other guy, I'm not sure. Maybe "theist"? My impression was that they're an open-minded and diverse group of people. Maybe you can find something similar in your area.
And as you say pub attendance is down by a lot too.
The major lack of easy association to the group is something that is hard to replicate in the nonsecular space. There is nothing strongly compelling about a group that's focus is too general, and the difficulty to bridge the gap from outsider to inclusion can be too high for a group that is interesting.
You mean other than the focus on God and morality?
