I'm not an expert on this subject, and what you stated may well be true. However, we (us seniors) grew up with that sort of TV violence as well but we all (my friends, family, etc.) knew it was acting and special effects. As a quick example, many of us, myself included, watched the 3 Stooges but we all knew that you could not whack someone on the head with a crowbar or a 2x4 in real life. We knew it was slapstick. Granted, things are far more realistic today but nonetheless, to say that children are learning this from the media seems weak to me. Perhaps it has more to do with real-life violence. It's how various governments resolve issues, they go to war. It's how the bullied take vengeance on their tormentors. Unfortunately, it just seems that humans cannot tolerate differences among themselves, be it religion, skin color, ideology, or even which sports team one supports in some cases. Violence always seems to be the go-to way to resolve things.
