Huffington Post which addressed Christian communities that believe children are practicing witchcraft. The examples were extreme, but it made me think of the evangelical circles in which I travelled, where people CONSTANTLY referenced sickness, calamity, and death as being the result of evil spirits. People feared granting these spirits a "foothold" through music, tv, movies, alcohol... almost anything you can imagine was a potential doorway for giving an evil spirit power in your life circumstance.
I know that not all Christian churches speak this way, but in my previous church community and the church communities I grew up in, someone might mention that they were under attack by Satan as casually as they might comment on the flavor of their morning coffee. I contend that this superstitious view of reality is bad, bad, bad for the psyche.
I have been out of the church for 2 years and an Atheist for about a year. The amount of good and bad in my life is occurring in exactly the same proportions as before. Seeing evil spirits (or divine favor) in your circumstances is no different than imagining a cloud formation looks like Scooby-Doo.
