As someone whose spent a lifetome on the fringes, I think cultural identity has a strong influence on one's world view. At first, I thought I was becoming more and more alienated from the JWs at the KH and the other students at school (roman catholic system), because I couldn't reconcile the two belief systems, nor could I really agree with everything offered by one or the other. I thought I would find the religious or philosophical worldview I could identify with solely on how closely it matched known objective reality.
I realized though how the degrees of sympathy I had for one faith/view or another, wasn't just strictly on whether I felt one was closer to "the truth". It was also greatly influenced by the people I had contact with from those religious sub-cultures. The way they treated me, and especially how they treated those I felt were the needy in society, made me take a second look at their particular religious and philosophical take. It either drew more or repelled me from that sub-culture. Even as a severely impaired and awkard social animal, people were an important part of the picture for who I was at that point in time.
Just my own experience, as an alien in practically every group I've ever been in.
