However I disagree slightly with this statement "American kids watch way too much violence on TV. American children watch an average of four hours of television every day"
My nephew and his mates, though not American, are the same.
I would say kids in general today, around the world, have graduated to watching and playing stuff that in the past were strictly "Adults only"
And in general I see kids today, not just in America, behave in a far more violent manner than years back. The kind of cussing they do and threats they make when angered, for example, is shocking.
The difference being that American kids seem to have easier access to guns. Take away that ease and they may very well turn to other "weapons" should not sanctions be made to prevent kids indulging in such violent filled past times.
The problem is many parents, including my sister, see no wrong in such entertainment. They honestly over estimate their kids, assuming them to be way more intelligent and cultured, to be above committing such atrocities. Kids are kids after all. They are vulnerable and easily influenced, hence should be protected at all times!
