I’ve attended Unitarian Universalist services and had some UU friends who confided in me their feelings about their own religion(?). They as a rule are “feel good” people in search of truth but for the most part very atheist or agnostic about finding it in any one of the major world religions, and therefore they tend to take all the religions under their wing. Sort of like being married to seven wives but not really married to any one of them.
They tend to be educated and skeptical about the claims of traditional religion … liberal on the whole and sometimes libertarian.
I found it very difficult to bond with any of them, just as I think they find it very difficult to bond with each other, which may account for why have have always been and will most likely remain a very small group and yet very influential beyond their numbers in the political and social scenes.
