Express your concern about an emotionally unsuitable person leading a country while acknowledging their possible mental health issues.
I have often suggested Mr. Trump is a sociopath.  I contend his behavior certainly supports that conclusion.  That being the case, we do, indeed, need to feel pity for him as an emotionally disturbed individual.  At the same time, I am concerned that we have such an emotionally unfit individual as president.  IMO, the presidency is not suitable occupational therapy for a sociopath.  Gary Crum
