In modern history, hasn’t violence always been a part of entertainment media?
Of the top 10 in this list: http://boxofficemojo.com/alltime/world/ I count 5 that could be considered to have significant violence.
Asking me to watch a violent act and asking me to commit one are not the same.
The difference is in what happens to the viewer/participant. When I watch the movie bad guy murder somebody, I can side with the good guy who’ll eventually bring him to justice. But when I’M the bad guy, that choice evaporates, and I take a side which I shouldn’t.
That may not present a great problem in adults (though I believe it does.) But who could argue that it’s not damaging to children?
Anyway...We can’t complain about the state of our nation when we permit this sort of thing among ourselves and our posterity. We ingest all sorts of filth, and then scratch our heads in wonder when we get sick.
