He's insane. Just recently read about how he said there was a 'green' light around him as he spoke to the UN leaders recently.

Not to mention the recent 'invitation to islam' letter he wrote to President Bush.
This guy is a nut job and a scary one too.
Yes, he is. He displays what is technically called a paranoid delusional disorder. Pure Paranoids such as Ahmadi are often well organized, have no signs of psychosis such as hallucinations, ambivalence, flatness of affect, etc. They can in fact appear quite "impressive" to naive observers, for this reason. Plus, they do not necessarily display the paperback "someone's after me" symptoms often associated with paranoia.
Fortunately they do not necessarily act on impulse, and they are prone to become obsessive as a substitute, but are capable of acting on their delusional premises. In short, this turd needs killin'.
