Any station can air some movie at 4pm featuring the good cops shooting the bad guys. Or, for instance, it is easy to be watching some news report at dinner and being exposed to something beating the horror or gore movies by points.
Aren't kids exposed since birth to the notion that violence becomes acceptable if against the bad guys? Where goes the moral of don't to others what you don't want to be done to you?
Even some very successful animated movies like Lion King end up with the bad guy being killed. Either intentionally or not, kids end up satisfied that the bad guy had what he deserved and that all become happily ever after.
I'm not for one side or the other, I just wanted to raise some questions to see what you guys think. I don't think video games are bad for children, but I agree they have to be picked appropriately for their age. But I also think we end up avoiding violence in the obvious places but letting kids completely exposed to it in another ones.
