because the notion that everyone - in the traditional
societies you're talking about - is responsible for the
well-being, teaching, admonishing etc. of children
is legitimate, it can and does work well in a lot of situations.
I think what has happened (blame it on Hillary?) though,
is that that sort of warm and fuzzy imagery is put forward
to cover an agenda that's really about bureaucrats having
a free hand to drug and indoctrinate children and putting
parents in a position where they can be punished or at least
ignored if they object.
So we have reason to be wary.
