The only issue I have with that, is you seem to apply that to everyone. I grew up playing too much video games and watching alot of TV. Granted now I hardly do either, but it never caused my upbringing to falter because of that. I am pretty self-aware of my faults and problems, but none of that is correlated to TV and Video Games.
However I will divulge that I do think kids need structure and a healthy balance in terms of recreational activity. A little bit of video games here, a little bit of playing outside there, reading a little bit here, etc.
I do think we share the same family values and how we want to raise children, or in your case have, but I'm just careful not pointing the finger at certain types of media as a cause.
I do believe that there are very few movies suitable for a family. I check every movie on a web site called dove.org, which will literally break down every single incident that could be considered "immoral". I mean they'll even give you cuss word counts on minor cuss words like but*, cra*, and hel*... etc. (I slightly censored because I'm not sure if I can spell the word out on the forum)
Anyway, after looking at the most seemingly "innocent" movies, they actually all practically contained sever shrewed words at the least. In entire days at my home, I never hear any of these words, so my wife and I decided - when we put God first in our homes, we lock the world out of our home, so why let the "winds of the world" blow through our house? We wouldn't allow those words to be spoken by any member of our home, so why would we let the "invited guest" say them. (Here's a great short story called "The Invited Guest" http://www.sugardoodle.net/Television/The%20invited%20guest.shtml
You'd be surprised... Just check out some movies on the dove.org site, and its pretty straight forward. There's other forms of objectionable content as well, such as cleavage and disrespect towards parents cited.
The same generally goes for video games, filled with magic, violence, and other objectionable content.
No, its not everything (well with TV it practically is), but I do believe that the "stupidity" the OP was talking about was why do they do such horrible and stupid things without thinking etc. I believe they have filled their minds with poison, and often have anti social problems because of it.
Don't get me wrong either, I wore out the old 8 bit nintendos and Atari 2600 systems... But they weren't as real, time consuming, nor the games as sick.
I think I've told this story here before, but if I haven't, on my daughter's 13th birthday (she's still 13), I cornered her. I said "________, okay you are 13 years old now, and I've never heard you once say a bad word. Do you even know any bad words?" She said while looking down and glum, "Yes I do know a bad word". I say "well I want you to tell me what it is that you know, and where you learned it". She said very shyly and under her voice "fart".
She learned it from me because I played pull my finger with my 3 year old and later told my wife about it and told here how I was dead accurate on the fart...
But anyway, I really love to keep the children "innocent", and away from the "winds of the world". Later as rational adults, with the full understanding (including in abstract) what sin is, they'll learn plenty from this world needing healing. I just hope everything I can teach them will stick, and they will have a "the armor of God".
