Sounds kinda like atheist churches. Something that looks nonsensical on its face, but actually makes sense when you think about it.

One of the really beneficial things about religion is the sense of community and the ritual of going to church every week, singing some songs, etc. It’s a great place for religious people to meet people, make friends, and establish a good social life that can even extend outside of the church itself. So why not do all those things, but without the magic sky fairy?
