I don't agree with you, it depends on the context - Indoctrination of religious belief may not involve telling kids they'll go to help, it depends on the method being used - I could tell my kids that they must really believe in god because there's lots of evidence and there's none for other gods, and they would believe me (most likely)... Political ideas can be as dangerous if not more than religious ones, and they can cause a lot of hatred and intolerance
