It's sheer Narcissistic Personality Disorder.

He has a grandiose sense of self-importance, a complete lack of empathy, tremendous insecurity and a need to receive constant attention, regardless of whether or not it's positive.

Coincidentally, quoting personal heros as "omniscient experts" (i.e. Vinth with Boortz) is another characterisitc behavior of the narcissist.
