Our bi-polar press

Why is the U.S. press fixated on binaries: black/white; up/down; win/lose; good/bad; pro/con? Is both siderism merely a matter of convenience and/or laziness? The press, probably because of Franklin’s influence was given special recognition in the Constitution and has used it as a license to deceive and obfuscate.
So, when Donald excoriates the fake news, it seems fair to conclude “it takes one to know one.”
