summary from the Mayo Clinic...here's an important excerpt...
------------------
Narcissistic personality disorder is a mental health condition in which people have an unreasonably high sense of their own importance. They need and seek too much attention and want people to admire them. People with this disorder may lack the ability to understand or care about the feelings of others.
------------------
That total lack of empathy for others is key to making narcissism a disorder. Given my numerous posts displaying empathy for struggling immigrants, as one example, underscores the error in your assumption.
Think before posting, or at least understand what you're talking about.
