I see kids playing outside in the yard the whole day (in summer), do I have to conclude from this that their parents have no computer in their home, or forbid them to use it? Like, at all?
Hey, how are computers any different from board games for that matter? If a kid's just lazy and prefers sitting on his ass all day, then hey, no excuse is too bad, isn't it?
A couple of fallacies you make in your thesis:
-TV and computers only serve distraction and entertainment, and nothing useful can be gained from them.
-it's impossible to restrict their time, or, to an extent, guide their activities in those mediums, so the only solution is getting rid of them completely - along the way, sacrificing anything useful that may come out of them.
