Actually its not that black and white, ER. The UU movement has been considerably influenced by humanist philosophy. So much so that when I was a young adult, a lot of us found that the church didn't give much encouragement to spiritual viewpoints--rather, officially encouraged "reason and the scientific method" in the development of religious beliefs!

I'm am not disparaging the church, its a fine organization, just stating some historical stuff here. I know a lot of my contemporaries who didn't stay involved with the UU church at that time have since returned to it--often when they have kids of their own--its a good environment for families.
