Yes, there are bad parents out there, but good parents in this day and age quickly find out that it's them against the world.
There are too many anonymous armchair quarterbacks out there who go crazy and complain when they learn about parents who go the extra mile to discipline their kids. They care more about hurting the kid's feelings than about whether the kid becomes a better person in the end. Make your kid stand by the street and hold a sign telling how awful he or she is, they call you a cruel, Blow your teenage daughter's laptop apart with a .45 caliber handgun, they say you're a monster.
What do they know? Nothing. Nada. Zip. They haven't had to put up with your kids for the last few years, and you have. They don't care whether your kid becomes the next Nobel prize winner or ends up on America's Most Wanted, and you do. Don't listen to them. If your kid misbehaves, do whatever it takes to straighten them out.
