Facebook can never stop fake news, and still be Facebook
Alice Clearwater

..Breathing the stale air inside their filter bubbles, Americans’ political character is changing. Because it appears that my opponent’s views are fed by fake news (and to him that mine are, too), our mutual disrespect and intolerance grows. We further lose sight of a common ground where issues can be debated using a mutually-agreed-upon factual currency, which the democratic process requires. When that currency is devalued, or doesn’t exist at all, there’s just nothing to trade on–nothing to talk about.
