Please don't take this as a personal offense, but in my neuropsych class we learned that teenagers are in fact a special kind of stupid, due to developmental timing. Certain brain functions develop more quickly than others, and hormones make a mess of everything, and as a result teenagers are generally socially stunted, self-absorbed, risk-taking, and moody. For one, teens read use more gut/emotional responding in the brain than advanced frontal processing, so they tend to read more emotion into situations. Males also tend to be particularly gut-reactive. There's a lack of consequence-oriented thinking, which obviously has a not-so-positive impact.
Here's a good article - http://parenting.blogs.nytimes.com/2...teenage-brain/
And of course, everyone is still growing.
My consolation is that most of the asshole teenagers from my middle school seem to have actually grown up to be quite decent adults, and I'm friends with a good handful of them now via Facebook - it's neat to see how we've all matured. I was moody and whiny and rebellious then, myself. Given, of course, some of them hold political views I think are idiotic, religious views I think are odd, or are taking directions in their life that I would not choose to take, but that's their choice and overall most of them have panned out to seem pretty normal and well-adjusted.
I hope the guy talking about rape gets in a good formative experience soon enough that will change his views for the better.
