I had a similar reaction to the Roman Catholic church.   As an adult, while I do not agree with many of the beliefs of the Catholics, I have a greater appreciation of the liturgy and what it symbolizes.   
Also, here are two truths that each side of the church has to learn.   The right has to learn to be less legalistic and more inviting.  The left has to learn that there are indeed absolute truths and that not everything is permitted and excused.
