Erosion, usurpation, of parent rights has been going on a long time. From public school sytems, from government agencies, from voluntary organizations, and especially from increasing literature challenging parental primacy in education. And to be especially noted, from universities and faculties of education, sociology, anthropoilogy, ethnography, eco-psychology, political science, etc.
Biologically, practicaly every creature on this EARTH has been endowed with an instinctual sense to bring their YOUNG to a state of SELF-SUFFICIENCY.
This is why the matter of DUTY trumping RIGHTS is important to uinderstand.
