Grown ups find the idea of respecting children to be strange, to say the least. Children, I think they'd argue, are young and do not know much, and so should listen to their elders. Grown ups, on the other hand, feel they have no obligation to listen to children.

This leads to all sorts of problems, not the least of which is child abuse of various sorts since the kids quickly learn they'll just be dismissed out of hand.

This goes in other matters too. A child might not like their given name and so adopts a nickname which they prefer to be called by. Perhaps all their friends and most of their family call them by (or know them by) the nickname. But, of course, you will have the grown ups that won't. Relatives that refuse to or, worse, teachers.

In the case of relatives, there's not much to be done. If they're being particularly nasty you just stop having them over. In the case of teachers it's a bigger issue. A teacher has all sorts of power over children and isn't easily eluded. If the teacher refuses to use a nickname in favor of a given name, all they are showing is that they do not care at all for how the child feels. If they cared about the well-being of the child, they'd use the name the child chooses to be called by, not force them to endure day in and day out a name they don't like. Particularly they should never have the right to humiliate a child just because they can.

Children should not be forced to endure humiliation. They should not be forced to hug or kiss relatives either, since all this teaches them is that grown ups can, at will, force themselves bodily onto a child. They should not be told that their thoughts and feelings are of little or no value.

They will be anyway, with many grown ups approving and some calling for even more horrendous things to be done to kids because they, themselves, suffered it.
