This is nothing more than the old "authoritarian personality" canard that the left has been pushing for years. One of their goals is to diagnose conservatives and conservative ideas as mentally ill/pathology.
Just like they did in the old Soviet Union.
"scratch a liberal, find a fascist"
Thanks. I seem to remember something about that--clinically defining anyone believing in 'failed' ideas as mentally incompetent.
Michael Savage's book comes to mind...
