The Unitarian Universalist Churches are much different than almost every other church in America. It actually promotes freedom of thought and freedom of religion within itself. It has had a long history of independent thinkers before Unitarians and Universalists merged, and now welcomes agnostics (which I am), atheists, Buddhists, pagans, and many other religions or viewpoints.
When I was little I don't remember going to church ever. Though after my father died when I was seven my mom took me to a local church that happened to be Methodist. While I enjoyed my time there (except the boring services), I slowly started to drift away from it. The ethics of many conservative religious viewpoints and Bible thumpers never sat well with me. It wasn't so bad in our Methodist church but I live in what they call "The Bible Belt" and it's awful. After becoming more agnostic each and every year, I eventually became very non-religious.
I couldn't count the number of times at work or in another social situation where some random person came up with such motivation to make sure I believed in Jesus. And I was never foolish enough to admit my non-theism, because that turns into a big ugly mess. I quickly lie that I agree with them so they can move on and bother someone else.
