After I left the jw's, I still believed very firmly in a Creator. However, I was too hurt and angry and burned out by how religion had screwed over my friends and family, that I took some time off from worship. It just gave me such a negative feeling, I felt it to be counterproductive. After some soul-searching and much reading/talking/thinking/dreaming about the nature of the divine, I resumed regular prayer and worship, although no longer as a Christian. (For the record, I'm Pagan.)
One thing I've always tried to hold onto, even when I was a witness, is respect for the beliefs of others, even when they differ greatly from my own. I'd never throw mud on an American (or any other) flag, although I'm certainly no patriot. I'd never treat a Bible, Q'uran, or any other holy book disrespectfully, although these books don't hold any truths for me. I was most careful transporting my dead grandmother's Catholic statuary and rosaries from her home, even though these items have no connection to my own faith. So, I have to respectfully say that it does bother me somewhat when atheists and agnostics refer to God as "doG". It just seems like they're making fun of the concept that a lot of us hold very dear, and it hurts a little.
