Right-wing propagandists like Limbaugh and Coulter are essentially entertainers, entertainers who stimulate prejudice, selfishness and meanness the way a comedian works for laughs or a tragedian plays for tears.

In place of traditional conservative ideology, they offer their audience partisan belligerence and a complete package of mail-order hatreds, designed for the conceptually and ethically impaired.
