I see your point, to a degree, but...
If a person spends any time here at all, they will soon realize that the majority of the posters are adults. If you can't handle an adult world, then it's time to leave. Pick on him? Nah, we are simply educating him in the ways of the world. I would much rather have been picked on when I was a kid than to go through my teen years thinking everyone was going to be nice to me, all the time. That would have been a harsh reality check when I entered the workforce.
