The thing is, those are the people you're looking for! The ones who reject (or are rejected by) mainstream religion, but desire a welcoming community atmosphere, they end up at UU churches. If you find Wiccans and sky-children there, that's because they're present in your community, and sought out the church for probably roughly the same reasons as you. Who better to form a community with than nice people with whom you might not otherwise interact?
