America is a country of excess.
The people responsible for the dollars that will buy the sex and violence so many deplore, don't even know what's going - well, of course they know. But they're comfortably ensconced in their country clubs and churches, and very far removed from the decisions that are made on their behalf.
We are a country of excess. So it's not the violence, per se, but the exacerbation and constant repetition.
