Religion and god can be separate? if we compare both what is most dangerous #justasking
Not all religions even have a deity (Buddhism, Taoism, LaVey Satanism, etc). So sure they vary independently, although most often they are associated with one another.
What nearly all religion has in common is religious faith, the unquestioning acceptance of asserted truth without substantiation. Whether it's faith in god, faith in a holy book, faith in a practice, faith in some nutter cosmology, is beside the point.
The problem is neither god nor religion per se, but religious faith.
