I think the better case is that the religion requires its adherents to follow practices of child abuse/neglect/abandonment.

The foundation of the Abrahamic religions is in Abraham's torture of his child, Isaac, to prove his fealty to 'God'. 

This means the religion itself as well as the parents who put their children at risk by putting them in custody of the religion are in violation of the child's rights and accountable for addressing the problem.
