The media has definitely shaped today's kids, but I think the deeper issues is kids can't go out and properly express themselves.
When I was a kid (I'm 22, so I feel like I'm in the cross-over generation) I was always outside getting into harmless trouble.
Just recently I wanted to take my 10 year old step brother to shoot some airsoft guns and his mom was like
I mean yes, completely dangerous, but we always had 'armor' so we tried to have some kind of safety.
But like I was saying, we had a way to go out and express ourselves by shooting each other up the safe way, racing bikes, sparring, or anything and then we'd come in and be the best of friends afterwards. Now these kids are so sheltered I'm scared for the future because all the have is the media shaping their imagination, instead of the other way around.
But anyway, I hate this "PC" society, they're trying to shape isolation and it's only gonna lead to some evil ass kids
