@AoG Your reasoning seems to assume that any adult abuser of the child will be a stranger. Sadly, this is not always the case.It is better for everyone that children are made aware of the risks. Such awareness extends to adults and those in authority too, taking those kids that do report such issues far more seriously, rather than just brushing it under the carpet, or dismissing it as childish fantasy as seems to have been the norm in previous decades. Child sexual abuse most certainly is not a modern day phenomenon.
And Social compliance is extremely powerful, and not just in kids, either.Google Milgram sometime if you want to see just how far ordinary people will go just because of social compliance. But that is straying off the subject a bit.
How can you possibly argue with the notion that kids should not be forced into offering loving gestures, just because some relative demands it?
