I’m guessing that there are plenty of people who received stranger danger training as a child who were taken advantage of. They weren’t taken advantage of by strangers though. I’m not sure that who does the abusing even matters though. The abuse in the Church didn’t stop because the things that were being taught to children was so much better, it was the public outrage because the Church couldn’t keep it a secret anymore. So I doubt the effectiveness of these kinds of programs are all that people think they are. That being said, I think it’s appropriate to teach kids boundaries in school. I don’t see anything wrong with that.
From what I remember it was the Adam Walsh story in the early 80’s that sent parents across the country into a dizzy. All of sudden there was a great fear among the public about finding their kid in the woods with their head cut off. Then Mr. Walsh went on a crusade probably doing just as much damage as he did good. Not a fan of that kind of activism. He basically went around trying to convince everyone that their kids were in constant danger and t just a matter of time before they wonder off from you in a crowd, and poof their being kidnapped, tortured, molested, and slaughtered like an animal.
