I have been studying media for several years now. I have been exposed to all oulets, contrary to what someone on this site thinks..you know who you are. I don't devote my attention to one outlet, I watch them all and draw my own conclusions...being able to come up with your own opinions after keeping up with both right and left wing news sources... now that is rationality. And if you want to talk about rationality, this is what I have found to be a very acuurate depiction of world news and journalistic bias. http://www.honestreporting.com/. You dont have to agree, but you wanted a concrete source so here it is. Instead of narrow-mindedly sticking to your BBC's and CNN's, look into this as well. You will sound a lot more credible.
