As a psychologist who interacts with fellow atheists, I think one area we could all take a look at is how much our current beliefs and behavior continue to be affected by early religious and superstitious training. Assumptions about relationships, human connection, and especially sexuality are often areas that, as people floating in the sea of religious paradigms, we may simply follow along without questioning. Examples might include feelings of guilt that may come from early religious childhood indoctrination. In my experience, the guilt cycle is one of the most powerful religious infection tools. If you were raised in this culture, especially in a religious home, you probably got a strong dose of guilt. Simply getting rid of superstitious ideas about gods, does not get rid of these kinds of psychological responses. Sexual inhibitions area also a great example of continued religious influence. I have a good atheist friend in his 50's who has been an atheist since his 20's and still has trouble getting over inhibitions he traces back to his early religious training. That is pretty deep programming!
