I used to go to church, but......?

I used to feel that there was an 'A List' and a 'B List' in the congregation. I am shy and was looking for acceptance for my 'true' self - and I found that feeling very distressing. I believe very much in God, and there were some very wonderfull people at that church. It was more a 'group dynamics' type of thing such as you get everywhere. I feel quite sure it exists in all churches. I think it is a very destructive problem though, as over the 8 years I attended I saw a number of 'unattractive' people leave. Yes, I was as friendly as I could be. What do others think?
