The sad part of this is that the media's credibility has been seriously eroded - left and right.
But if we do not get our news through the media, where is it to come from?
There is no easy solution to this problem. The best you can do is to make an effort not to get all of your information from inside the same bubble and to be skeptical of everything regardless of the source. When I say skeptical, I don't just mean that you should assume that you are being lied to, because that may or may not be true, but you should also assume that even the truths are only part of the story as seen from one side.
The above is very hard to do for anyone, but especially when you identify or generally agree with one side. It helps if you try to maintain an intense hatred of both sides I think.
