Well if religion is like drug addiction, I hope the group "RR" (recovering from religion) uses a better strategy than "NA" or "AA" - The 12 step program is equivalent to religious virulency :)
Is Religion Really Like Opium ?
I've tried opium but have never been religious so cannot give a complete answer.
I have long said that religion is an addiction, much like an addiction to opiates ... and the first problem for some people who lose their religion is, rather predictably, WITHDRAWAL. People who have become used to the church or temple or mosque providing them with hope and purpose face a yawning void once they've dropped that structure. They may be further daunted when they realize that any hope or purpose for their lives will have to source from themselves and no one else. Oh, you can get help from friends and family, but ultimately, what they have to recognize is that each of them, individually, is the author of their own actions, that they alone are responsible for what they do.
I call it, "working without a net."
