Icon:  Mr. Trump, indeed, has no capacity for criticism.  We will see four years of that "thin skin" you mention.  I don't wish him physical ill, I would rather see an improvement in his "mental health".....perhaps an end to what I can only describe as sociopathic behavior.  I share your view of him as a narcissist...a part of a sociopathic personality.  
I'm not optimistic......when you make a egomaniac the most powerful person on earth, you are really "asking for it."     regards, Gary
