Hey, Tartarin (brat!)...Stuffed Pepper here.
I don't think it's wise to expound on my own personal beliefs here. I would only make myself a target for those looking for a fight in the name of "intellectual debate." You are right...my own beliefs do run as deep as you stated so well.
As to my actions, I simply consider myself a Christian. I have been a member of several organized groups for the purpose of accomplishing more as a group than I can alone. I've run into the same types you have, maybe even more often than you do, but I also know a lot of very good people who inspire me to be more creative, more forgiving, and more thoughtful of others than I usually am. Because of them, I hang in there.
Anytime you get a big group of people together for any reason...religious, economic, political, social, educational, etc....you inherently have infighting and political divisions. It's just a flaw in human nature. Churches are no different. Sometimes they're better, sometimes they're worse.
Hope that answers some of your questions. I welcome discussion, but I'm not looking for argument. I get enough of that at work.
