I loved the local paper all the way until they let go many of their writers, cut the content by a factor of three, raised the price, and stopped offering any hard news.
But I don't understand how any of that was polarizing. Can you 'splain?
You're describing the aftermath. They had to do that because too few loved them anymore.
How did the demise of newspapers contribute to the polarization of America? Well, once upon a time we all read the same version of events. It was called "the News", and it was vetted by educated people known as "editors", so that B.S. like the Kardashians, and other lies, didn't slip through into our collective consciousness.
We were all free to make our judgements from there, but "the news" was a universal thing that happened every day, and it enabled us to discuss things on a constant, level (and logical) playing field.
With the demise of newspapers, which we all once read, this universal conversational starting point has been lost. We no longer have a consistent point of reference from which to start a discussion of world events, since YOUR version of "the news" may be (and often is) radically different from mine.
Or, it may be the same events, but reported TOTALLY differently.
Thus, not only can we not count on knowing the same things before starting a political debate, we can't even count on knowing the same version of the same stories as those "known" by the person we wish to engage in debate.
Our compass, the newspaper, has been lost -- for better or worse.
