Actually my layman's opinion is based on the definition of sociopath and the characteristics described and my knowledge of the well-documented history of Mr. Trump's behavior.  BTW: It's a widely held opinion among psychiatrists who venture their opinions (they do usually state a real diagnosis would require interviewing Mr. Trump).  You seem to imply by your comment that Mr. Trump is, in your opinion, narcissistic.  That opinion, of course, would be based on your reading of the definition of narcissistic and the accompanying characteristics compard to Mr. Trump's behaviors.  We could quibble regarding the definition which best suits Mr. Trump.  However, I'd be happy to make the case for Mr. Trump being a sociopath any time any place.  While professionals are careful to "qualify" their opinions (since Goldwater's campaign), I am quite willing to share mine.  Read the definition of sociopath, read the characteristics, study Trump's history and decide for yourself....  Gary Crum
