For what it's worth, I still get a kick from time to time out of being able to recite long passages of Hebrew and engage in pilpul with my Jewish geek friends (both frum and otherwise), despite in no meaningful sense remaining a practicing Jew.
I also get a kick out of being fluent in Spanish and I've been known to enjoy hairsplitting discussions about Buffy the Vampire Slayer and reciting long passages of scripts of plays I performed in. I also get a huge thrill out of being able to recite the first sentence of the Oddysey in Greek. None of this has anything to do with religion or atheism, admittedly.
All of which is to say I suspect you can probably find atheists (both strong-sense and weak-sense) who share your appreciation for history, tradition, shared birthright, the intellectual pleasure of memorization, and learning foreign languages.
The comfortable feeling of safely believing the proper things, on the other hand... yeah, that one will be more of a hard sell, at least to talk about. (You will find many people in sufficiently large soi-disant atheist communities who enjoy this feeling, of course, like any other group of humans, but they probably won't admit to it and may well get upset at the suggestion.)
I agree that there's an actual problem with the "safety" of passively believing what one's told and I don't actually want that part back.
In the comments of a recent thread, another poster pointed out that religious individuals tend to report higher levels of happiness than nonreligious individuals. I suggested that the social network of churches, rather than the direct effects of theistic belief, might be responsible for this difference, and after doing a bit of searching around to see if the available studies support such an explanation, found a study that indicates that this is indeed the case.
Religious churches may be far from optimal in the services they provide to communities, but they have a great positive impact on the lives of many individuals. And not just as friendly social gatherings and occasional providers of community service; I've known priests who were superb community organizers and motivational speakers, who played an important role for their congregations to which I know of no existing secular analogue.
It seems probable that a secular organization could effectively play the same role in a community, but would anyone be likely to take it seriously? Since people who're already religious may be inclined to reject the value of a secular authority filling the role of a church, and atheistic individuals may not be inclined to attend, either due to reversing the stupidity of religion, or due to asocial and anticooperative values, it's uncertain whether a secular organization that adequately filled the role of a church would get off the ground in the first place in the present social climate.
So, what are your feelings on the prospect of secular church analogues? Do you think that they're appropriate or practical? Do you expect them ever to become common in real life?
