- This enables abusive parenting styles and forces adult children to need to unlearn this lie in order to come to terms with their abuse;

- This enables parents having an outsized influence on adult children, such as controlling their sexuality, interests, physical location, etc;

Frankly: the parents have an obligation to care for their children because they generally chose to have children or chose to keep them once they were had. The child did not choose to be born and does not have a choice on the quality of their parentage. It's unacceptable to then place the burden on the child for choices they didn't make and have no control over.
