A great number, if not the majority of the members of my local church are agnostic or atheist. There are quite a few who practice Wicca/wicca-influenced paganism. I’m one of the only Buddhists who regularly attends (AFAIK, the only one.)

I would love to hear from other UUs who are otherwise religious (especially Buddhist UUs) about their experiences! Personally, I love my congregation and I almost always have a great time when I go, but I sometimes find myself bored with some of the more secular aspects.
