I choose to be offended by the objectifying, denigrating, irreverance of Saletan's title. A 'hole' is a nondescript void in an otherwise solid mass or plane. Philosophically, a 'hole' offers no meaning, no value, only the absence of meaning and value. However, in applying this void to a context, it serves to denigrate.

'A hole in the head'- referring to someone lacking something in thought.

'Crawled out of a hole in the ground'- someone who emerged from nowhere with no value or meaning attached to him

'Go back to the hole you crawled out of'- meaning someone from a lowly, ignoble origin.
