Mr. Carter:  You make a valid point.  The vitriolic comments from many Trump supporters at his rallies is truly frightening.  Chanting for the death of a political opponent is not a sign of emotional wellness.  Mr. Trump, of course, with his own actions and statements, has encouraged such actions.
These actions are, IMO, clearly "deplorable." Mr. Pitner's "hanging effigy" of Ms Clinton is, again IMO, a tasteless display of hard-right-wing zealotry.

I do, however, defend the right to, within the applicable laws, make those "deploable" comments.  The First Amendment protects "freedom of speech and expression"...and the limits are carefully defined, protecting speech and expression we may find tasteless, offensive  and even potentially dangerous.  

I feel Ms Clinton's mistake was calling the individuals "deplorable", rather than calling the behaviors and comments "deplorable."  ...I see that as a significant difference....
