Hello Cypress,
It was a valid point. I just wanted to clarify the way it came across to me.
Part of the freedom felt when becoming an atheist comes from moving beyond the insecure feelings of being 'left out' of groups such as a church. There are all kinds of social groups which can be joined. Crafts, books, cooking, sports, bird watching, fan clubs, country clubs flaunting great wealth, yacht clubs, volunteer organizations, etc. Nearly all of them purposely stay away from religion because members can come from many religions or none at all. There are many ways to have the feeling of being part of something without being in a church.
But ultimately, the feeling of realizing that one is merely a human life form on a tiny speck of a blue planet, during a relatively short duration of time, orbiting a star, one of many billions of stars, all of them apparently moving away from the same point and dying out, and knowing that one is such an infinitesimally small part of that, but a far larger part of the human race? Well, that's just a feeling of belonging right there in itself.
You know. In the grand scheme of things.
Being in a church is not required in order to realize that we are all connected by simply being human.
