Okaaayyy, I see where this is going. Let's try this from another angle....
As a missionary in Nepal, what does he teach the Nepalese people to believe? Does he just hand out these "Billy Graham's Doctrinal Errors tracts" to them, or is there more to it than that?
He only preaches about things like this to people who are already believers.
There wouldn't be any reason for the unsaved to be taught what errors to watch out for.
He teaches Nepalese how to type hysterically in ALL CAPS.
