Whenever we get one of these events the calls go out for more censorship of media to correct bad parenting by individuals. Our censorship fans from the "Christian"right to the "anti-hate" left both think that Pandoras box can nailed shut. My wife recently got a phone call from some media censorship outfit my little sister subscibes to in an effort to control what OTHER PEOPLES kids are viewing, very disturbing. The wife gave them a piece of her mind!
Even at their young age, I've got my eye on the kids in my daughters class. Having had the advantage of being in high schools as an adult, I think I can anticipate some of the potential problems but we need to be aware. To address the first impression issue, I recently shaved my goat and let the hair grow back on my dome, giving the other parents one less thing to worry about
Jag mentioned depression in high school aged guys. I'd be more worried about teenaged boys who don't appear to have any signs of depression, in my experience they're the ones more likely to torment the kids around them, helping to create these explosive situations. Keep a close eye on football players, cheerleaders, and class government types, they are the real threat!
Seriously though, Xugumad touched the key issue. We need to be very balanced in our attitude toward childrens media. We can't let they become overly engrossed or totally deny them access... its damn difficult.
