Has it really developed. I know we have more knowledge, data but that doesn't stop ideology getting in the way.
Yes. Yes, it has. Even in the last ten years our understanding of trauma has deepened unbelievably.
In fact if we really followed the data then we should be finding that traditional parenting is the optimum way to bring up kids across a number of areas.
Well, first up, there's no such thing as one mode of "traditional parenting," so I think that assertion falls apart when we examine the first underlying premise.
Put it this way kids and adolescents are more unhappy, more disturbed, more suicidal, more badly behaved, more neurotic, more narcissistic than ever.
Evidence for each of these claims, please. Because just looking at suicide, it depends where in the world you are, but overall I'm seeing the most recent data claiming a modest recent drop in youth suicide rates.
So what exactly are the New discoveries doing exactly because they are not helping kids to become better people but their actually getting worse.
The new discoveries are probably more relevant to helping adults become better parents, than helping kids become better people (although I'll posit that
not having PTSD from childhood abuse would be objectively "better" than the alternative).
If the State is indoctrinating children with one ideological belief about morality relating to child behaviour and a family or families have a different belief then this is actually creating a conflict in the child. Its actually undermining the parents right to bring up their child in the way they see fit.
Well, not that I'd agree that the state is indoctrinating children, but of course part of growing up is realising that society is bigger than your family bubble, that other people have other ideas, beliefs, and ways of life, and learning the maturity to behave appropriately in a pluralistic society. Denying children that "conflict" would actually be to fail to equip them to take their place in adult society.
But it still has nothing to do with abuse or corporal punishment.
