Yes, parents are being straitjacketed by the fear of Child Protective Services taking their kids away. Child Protective Services cares more about whether the punishments dished out by parents upset or traumatize the kids too much instead of whether or not the punishments actually stop the misbehavior the parents are trying to stop. Sometimes punishments that some so-called "experts" consider to be "cruel and unusual" are the only punishments that actually work.
