My main problems with young kids playing online games is that it teaches them to be disrespectful and to have an unjustified ego. The other day I saw some kid around 12 wearing an Advanced warfare tshirt screaming profanity at his mother at the grocery store. That shit did not fly when I was a kid. These days the snotty little punks go online and run their mouths to people that could kill them in less than a second in real life, because the internet shields them from consequences. They then take this attitude of invincibility into their daily lives and act like contemptible little shits. Even worse is that if a parent dare smack their kid to teach them a lesson, CPS comes and puts them in jail. Nothing good comes of kids playing online games.
