Do you not think that organised religion is brainwashing?
Children should not be allowed to join a religion until they are at least 18. We outlaw other unsafe activities and decisions for them because we say that their brains are not mature enough to make those decisions.
But we brainwash them with stories and fairytales about invisible beings watching their every move and we scare them into thinking that their bad actions will be punished in a made-up afterlife.
@juglugs @IncredulousMike So many implications in this question that it can't be answered. I reject the premise of your question.
Quod erat demonstrandum.
