We're rather similar in a sense, both being ex-christians. I only have a vague idea of the type of Christian you were in the past, but I was a full blown agressive Evangelical. I generally consider myself from that period to be both brainwashed and insane.
I was wondering if you ever had any residual guilt, and ligering religious thoughts and ethics. For example there are many things that ethically shouldn't bother me, given my rejection and disgust with religion. Yet sometimes I still find myserlf concerned over it. It almost feels like there were certain things programmed into to me, that I still haven't managed to shake after all these years. After I first became an Atheist I'd keep catching myself 'talking' to God among other things. I'd get rather frustrated with myself for things like this. The effects are much more subtle now, but they're still there and it bothers me a great deal.
