Why does the girl dislike American TV programs?

M: Shall we watch TV for a while?
W:I don’t like American TV. People keep hitting each other and shooting each other.
M:Some of the shows are pretty violent. But maybe life is like that.
W: I don’t believe it. The people I’ve met here are very kind.
M:So are the people I know. But look at the newspapers. There’s a lot of violence in every newspaper. Most of the news seems to be about crime.
W: Maybe nice people aren’t interesting enough.
M: You’re probably right. People won’t buy newspapers unless there’s exciting news in them.
W:Is that why there’s so much violence on TV? Won’t people watch a show unless violent things happen?
M: I don’t know. A lot of people like shows about the Old West, with cowboys and Indians attacking each other. I don’t like them myself.
W: Neither do I.
M:They don’t show hoe people really lived in the Old West.
W: Of course not.
