I agree with PK. My biggest issue with organized religion is the whole god has a plan thing. I can't wrap my brain around other people being chosen to suffer, so I can learn to be a better person? That I can never wrap my brain around. Nor do I want to. It's dehumanizing and distasteful to me, and always will be.
That being said, religious tradition was so ingrained in me, as a child, that I take great comfort still in those traditions. I could certainly choose my fellowship without being a part of religion, but I like the community I found there.
