I think this is about young children being reared with a solid sense of values which have to come from somewhere. If we were brought up with no values or respect for society we would all be running around like savages. Many religions, Christian, Jews, Muslims, Sikhs, Hindus, etc, have many basic values in common which focus around being honest and caring citizens in the culture in which they live. If you don't want your child to be raised in a relgious background, how would you teach him/her that it was wrong to steal, to be violent,., to kill, to be selfish and all the other good attributes of human nature. Most of the better sides of our characters are in some way moulded by religious tenets and beliefs. If a child is not bought up with any religious background at all, how will they have the knowledge to decide whether or not to adopt or reject it when they become an adult and have the power to reason things out for themselves?
