Who said it's either/or?
I suppose you could say that it isn't, given that even while unsuccessfully pursueing the WOD, we do attempt to "educate" our children about the dangers of drug use.
But most of them understand that what they are hearing is propaganda, not education, so we are unsuccessful there as well. Some of us remember "Reefer Madness", a ridiculous attempt at propagandizing via film. In colleges, it was often considered great fun to watch the movie while getting high. Why? Because everyone who had ever smoked pot knew that the movie was a lie.
There are two main hazards associated with the use of propaganda. First, those being subjected to it may (and often do) come to lose all respect for the law and authority. Second, the propagandists may come to believe their own lies, to their ultimate undoing. There is ample historical precedent for this, dating back at least to ancient Rome.
You know, one good working definition of insanity is to keep doing the same things, expecting miraculously to achieve different results.
