Thanks for reposting! I have been reminding myself to go back and check.
And I guess by "atheism scale," I meant the grid V posted but also a "how much do you wear it on your sleeve" kind of thing. You can be 100% certain there's no god but also generally keep that to yourself or you can be Ricky Gervais, who tweets about it daily. (Not unlike religious people, some of whom pray quietly to themselves, others go to church, others are very vocal about it, and others are Jerry Falwell.)
As for paying, I did learn that the local Ethical Society charges for the (equivalent of) sunday school. I think it was $150 for the full year, too, and it does make some sense, because there are a lot of materials involved. Interestingly, preschool kids are free and grade school kids have to pay. They do have hardship scales and things, too, I believe, so the $150 some people pay would help cover those who can't.
I'm sure we'll have to do something about this eventually. I went to the Ethical Society one Sunday to check it out. It was OK, but I don't know that we would quickly be part of the community or anything, if only because of how far away we live from it. Another friend who joined said he finally felt like it after a year or more (then he moved to another state). I'm sure it will come up eventually when kids at school start talking about church and my kids are all "what's church?" I'd like to start taking them to secular things before that happens to try to preempt it a bit, but we're such homebodies that going somewhere on a sunday morning just seems unnecessary at this point.
