Having been raised Unitarian Universalist, I always find it very odd that "religion" is conflated with "unquestionable dogma". I don't think Unitarians have that any more than LessWrong does.

I was raised a Unitarian Universalist too, by agnostic parents. It probably has a lot to do with my generally positive attitude towards religion. (I now sing in a High Anglican church choir and attend services regularly mostly because I find it benefits my mental health.)
