@futurebird Adult child of spankings here and I concur! I've raised 3 kids without spankings and they all turned out great and are successful young adults. There was nothing a spanking ever did for me besides make me feel scared and unloved. Spanking humiliates children. It makes them feel vulnerable to adult anger.
Spanking is abuse perpetrated on a smaller, weaker person by a bigger, stronger person who has lost control of themself and run out of better ideas to modify a child's behavior.
