So, do you think religion is an addiction? If so, does that mean you think it can be cured? A 12-step program for overcoming religion?
I think there are some people who fit this model, people who are obsessed with their religious delusions. Unfortunately my first-born son would often get this way during a manic phase. He had bipolar disorder. Once when he was very manic a fucking Fundamentalist preacher sat him down to watch the Jimmy Stewart movie "It's a Wonderful Life" and the next day he committed suicide.
Usually the word addiction is reserved for cases where a repetitive behavior is thought to be harmful to a person. Alcohol can be addictive for some people, yet many others take it or leave it with no harm.
Religion is much the same. In small doses it is like the slight traces of toxins in many foods, not enough to hurt you.
As the dosage of religion is increased we see destructive behaviors, like preaching homophobia, invading foreign countries based on a pack of lies to please Jeebus, and my son hanging himself to go live with his Imaginary Bearded Sky Daddy.
Our bodies have organs like the kidneys and the liver to help deal with poisons we ingest. Critical thinking and skepticism can help protect us from poisonous ideas.
People can become addicted to poisons, but it does not always happen.
Like any other poison, the smaller the dose of religion, the better your chance of surviving the experience.
