Indoctrination is a word often used and I firmly believe in indoctrination. Indeed, indoctrination is a good thing, the only issue surrounding it, is the issue of what you are indoctrinated with.
The believers should only be indoctrinated with the Word of JEHOVAH for within are the words of life!
As I always say indoctrination is not bad, but what are you being indoctrinated with, for at the conclusion of all things there will only be two categories...........sheep/goat, righteous/unrighteous etc......
May his name be praised for the holiness of his doctrine.
