How to Tell You've Been Indoctrinated

[Angrboda]

I'm not sure what you mean by "indoctrinated." It seems you're using it as a synonym for brainwashed, which is a concept of some ill repute. If we were to rephrase the question as, "How do you know when you've learned about the existence of God?" then the question tends to lose the rather negative attitude involved by using the term "indoctrinated." I think you're biasing your conclusions by using loaded terminology.
