"Handling" ones emotions is a learned skill that must be taught. Unfortunately, many of todays children seem to be quite spoiled, allowed to throw temper tantrums in public, yelling back at their parents, or even striking and hitting them. In my younger days, we would not have dared such behavior at risk of being spanked in public, slapped, or worse. While I certainly do not believe in bullying or abuse, for both dogs and children to learn, there must be positive and negative consequences. That is all their brain is capable of understanding until it reaches a more mature level of reason and understanding. Ideally much more positive than negative, but they need to learn that a hot stove burns, an ice cube is cold, and that bad behavior results in bad consequences. Those same tantrums and uncorrected behaviors as children lead into the uncontrolled behaviors as teens and adults. So yes parents, it's your fault. Address it early, or see them in jail or worse. Now that's not to say all in jail or bad behavior is a result of poor parenting, yes some are just out of control sociopaths like a rabid dog regardless, but that is a far fewer minority.

I completely agree. I also believe that the few times I was spanked, my parents didn't do it to hurt me physically, it was more of a shock kind of thing. The lack of physical consequence online, makes people believe they can say and do anything without facing consequences. And now we see it in the streets.
