You made some valid points. Video games truly gets all the blame, while books and movies pose the same threat. But this still validates my point. We should remember that kids imitate what they see and there is the risk of terming it as normal.
Its true that when they become adults they won’t necessarily engage in this activities they play, but I don’t want to start mentioning instances when teenagers do unthinkable and horrible things…which they played as a game.
In the end, it is all in the hands of parents.
There are reasons the restrictions are there, and it would surely make things better as compared to without.
