Everybody that keeps using getting whoppings as a reason for adult failure sounds dumb.
There are so many things that go into raising a child and why they turn out the way they turn out. This argument falls apart when you point out the many people who got whoppings as children that are successful in their adult lives. It also falls apart when you point out the people that did not get whoppings who are failures in life. Things affect every child differently.
Too many people like to scapegoat their parents as the reason they ain't shiit in life. Sometimes, just sometimes, people are just destined to be bums no matter what.
