There's a deep irony here.  Prof. Porter has career-long expertise in "intercultural communication," but there are no signs in this expostulation that he has attempted any communication with the "culture" of Trump voters.  Instead, he has sorted them into his own three circles of hell.  The least of them, we are informed, are guilty of greed, and others have "winked" at "truth-bending."  I couldn't vote for Mr Trump, either, Prof. Porter.  But I decline to believe that well over 60 million of my fellow Americans are either "racist, anti-Semitic, xenophobic, homophobic, or anti-Muslim" or willing to tolerate same.  I'm listening, and I sincerely hope other serious minds are doing likewise.  Closed minds contribute nothing.
