Psychiatrist concludes that today's self-harmful liberalism is a mental disorder. Agree?

He's one out of thousands of doctors who could say the same about the Republicans. So what one person thinks about a group of people does not influence me because I know that it's their opinion and not fact. Come to me with several others saying the same thing and I might listen. But while it's only one persons opinion what's to listen to. I know psychologist and psychiatrist and social workers who feel the same thing about republicans.
