Everyone SHOULD read it, and it is often a distressing experience to do so. Back in 1929 it was internationally recognized that children in particular needed to have a codified set of rights, it has been improved on since - in many ways it is still not perfect but it needs to be understood that the rights contained within are the BARE MINIMUM.
If any of these are breached - whether on the home scale or on the cultural one, particularly for signatory countries - that is a fundamental issue.
I promise that learning what the established bare minimums are in universal human rights frameworks will enable you to cut through so much propaganda immediately.
Children and teens are full human beings and by becoming parents an immense responsibility is applied to treat them as such. They need open and clear communication, not to be talked down too, and to have their questions answered. They have the right to autonomy and life.
