So their belief is based on complete assumption that their parents and religious leaders are correct about religious matters.
And that belief is very powerful. I now think that a parent should be very careful about what they are dogmatic about. Teach children to demand evidence. Because they will accept what you say as gospel- and it will stick in their heads for a long time. (which is why it is very difficult for "raised in" witnesses to completely break free- there are a number here who have- but many more who haven't)
That automatic assumption that your parents always did and still do know whats right keeps people from looking at the rape, murder, torture, killing of children, genocide, mutilation, racism, sexism, xenophobia, homophobia described in the bible as wrong. After all, when Isrealites or 1st century Christians committed these crimes- they were doing the will of God. Only good parental programming and indoctrination can teach a person that these acts are the actions of a "loving" God.
A rational, non-indoctrinated person would automatically see these actions as repulsive.
