Gaming as a form of entertainment is never dangerous. As a means of escapism however, it can be dangerous if it becomes an obsession, but it is never a condition, it is a symptom that can be caused by a number of reasons and is no different than any other other form of obsession. When I was a teen, my daily routine was quite depressing, because there were only three male students in my class, which were not very good people, and the girls wanted nothing to do with me. In order to deal with my loneliness I became obsessed with books, to the point where I would be reading for up to 12 hours a day. Nobody saw anything wrong with that though and my parents adored me for it. That wouldn't have been the case if I had been playing videogames instead. Why?
In my opinion it's time to get rid of the stigma of gaming and start thinking more like responsible adults for once rather than paranoid headless chickens. Parents should do their best to be aware of their children's problems, get to the roots of their behavior and help them deal with the harsh and sometimes bleak reality of their everyday lives, because that is what usually leads to obsessive escapism. People like this psychologist with their big words, useless comparisons and hysteria aren't helping anyone apart from their pockets.
