Alright, boys and girls, let me tell you right off that my post is biased, as I work for a newspaper.
So, for my first statement: The media is not lying to you.
You are just being paranoid. We are not out to get you and we are not trying to control your minds. A lot of news is negative because that's what news is. Recently it has been very negative because we're in a war where we're suffering quite a bit of human loss. That's negative, sure, but people want to know that we're suffering human losses.
Should the media actually lie to you and say that the war is all sunshine and happiness and cupcakes? Or should they say that Kim Jong Il and N. Korea are not developing nukes, but rather giant missiles of joy and prosperity that he plans to share with everyone? Or maybe they should say that Ed Bradley didn't die today, he was just playing a huge practical joke. (Bonus points if you knew who Ed Bradley was without looking it up.)
We're in a negative time period right now. We're in a war, there's international conflict and trouble in the homeland as well. What is the media supposed to do, not report it?
There are happy segments when truly meaningful happy things arise. The NY Times did a cover story recently that followed a field medic in Iraq who saved a soldiers life after being sniped in the head with an anti armor round. The article had some shocking things in it, but all in all it shows that we're sending out well-trained people to save our soldiers.
Once you boil everything down though, you have to understand that it is very hard to find positive things to report when you're surrounded by conflict and disaster.
