"non-religious"? every being on the planet is religious how about the religion of tolerance the religion of alcoholism the religion of eating the religion of getting up every morning the religion of eating baked beans the religion of skateboarding the religion of singing a bird song in the mornings

booze can be your main god rock-climbing can be your secondary god sky diving can be one of your pantheistic gods self confidence, via healthy, living can be your god some imaginary dude with a beard can be your god. the spirits of the forest can be your gods caesar can be your god horus and isis can be your gods marilon manson can be your god sado masochism can be your god a pet dog can be your god a belief in aliens, along with plenty of sex can be your gods - as in the case of raelism silence can be your god
