Most people in my family and my HUGE extended family spank their kids. Generally the kids that don't get spanked are usually weird, creepy, ackward, and/or annoying. Fortunately, they tend to grow out of it after they grow up and leave home.
All too often parents that don't spank kids produce kids that are major POS's.
They're arrogant. Think they can do whatever they want without consequence. My guess is most politicians were never spanked as kids.
