Yes, I remarked to myself some time ago that Rush would lose his pissy edge since there was nothing to bitch about. Well, like a spoiled woman, these people live to complain.

The metaphysical reason is - lack of an organizing principle of faith. Most of them are too stupid to think abstractly, too heartless to feel genuine compassion, too rigid to enjoy experience, too repressed to enjoy the pleasures of the body. Thus, they are left with nothing to believe, enjoy, or accomplish. Bitching becomes an end in itself.
