Good for him, but it's not whether people are bothered by it or not, it's that you always seem to feel the need to say it.
And, like Pitts, you have a right (no quotation marks) to state your opinion about this.
I can't think of any reason not to call the MSM the "Dinosaur Media" - their declining audience base and readership alone point towards their continued shrinkage if not extinction. And then the snarky condescending attitudes that they have towards the America that they don't much care for, the so called "flyover country" - alienating potential audiences is not the "smartest" marketing strategy. I believe I saw a stat yesterday that FoxNews audience share is now 4 times that of CNN. Furthermore, the term "MSM" implies that they are "mainstream" when they are anything but mainstream, so I and others have searched for a term with which to label them. I think that it was either Laura Ingraham or Anne Coulter who first used the term, and it stuck because it fits.
I would prefer to have a balanced non partisan media, but those days are long gone. Someone will write a history of this one day, but I think that we can thank the original Big 3 TV broadcasters, CNN, The New York Times and the Washington Post for first putting us on the path to our current era of partisan media.
