There's no doubt we're in this awkward generation where our parents were probably treated with corporal punishment, but still want to inflict onto their kids this which they were exposed to as a kid despite this no longer looking good/being legal. Even the anti-child-abuse book "For Your Own Good" by Alice Miller wrote "The former practice of physically maiming, exploiting, and abusing children seems to have been gradually replaced in modern times by a form of mental cruelty that is masked by the honorific term child-rearing". Of course the book pretty clearly covers the dangers of corporal punishment or any kind of attack on a child's self-worth. The point is to push through this awkward abusive phase and bring our species out the other side more self-aware by not continuing the cycle of abuse/neglect.
