text: Mr. Murphy's OpEd piece exposes today's toxic political environment and suggests the sources of that toxicity.  Your response is the all-too-predictable:  "Blame the messenger."   
  
    OpEd pieces are, by definition, expressions of views and opinions.  Sometimes they reflect particular expertise and experience,  but often writers address issues "outside" their personal arena of expertise.  Mr. Murphy may be, by profession, a geographer, but that hardly negates the value of his perceptions regarding other issues.  I found his piece quite perceptive. I'm guessing you didn't. 
  
  If you disagree with his views, by all means, publish a rebuttal....perhaps an OpEd piece of your own, or, at least, some substantive rebuttal on this site.  If you feel Mr. Limbaugh and Mr. Hannity, for example, don't promote divisiveness, make that case.  If you feel Mr. Trump's campaign isn't founded on anger and resentment, make that case.  If you feel Mr. Trump will "make America great again"...tell us how...
