If a person has never encountered a god concept, then and only then, can he make a free choice to become a believer. most people are either inculcated, indoctrinated, or influenced. But even then the guy who never encountered the concept may be unduly influenced, once he had come to know of it, especially if he never learnt about it for himself. So it may never be a free choice.
True never a free choice but influenced from birth.
Everyone is born to parents.
Parents have a duty to bring up their children in a moral ethical way.
If one cares about ones children they would realise they are innocent bystanders observing them.
They are the moral ethical authority.
What they say and do influences the innocent child.
If the parent does not follow a moral ethical authority of the self then the child see no reason to either- its has no authority of its own learning process to pass on as an authority.
The indoctrination is when parent, teacher, political or monarchical authority does not do what they should do but tells others lower down the consciousness bracket what they should do. Such positions of power should be made aware of their negative influence on the innocent.
People ignoring the presence of the innocent is less aware of their influence and the direction they are taking humanity in.
It is always good to have a authority of higher morals if we want peace in the world and peaceful co existence. It is what the Theists promote by saying God said.
