Amanda notes below that both Hugh Hewitt and Mary Katharine Ham can claim the distinction of having been named Keith Olbermann's "worst person in the world."  If one is known not only by the quality of one's friends but also by one's enemies, I can't think of a higher compliment.

What's always amazed me is the clownish narcissism of Olbermann's designation of his own political adversaries as the "worst people in the world." 

Really?  In a world where, among other events, Islamofascists want to kill innocent people, the Myanmar government refuses to accept aid for its desperate people, Fidel Castro has consigned pro-democracy activists to prison -- and, even in this country, pedophiles and child-killers exist?  And Hugh Hewitt, Laura Ingraham and Mark Levin are the worst people in the world as far as Keith Olbermann is concerned?

If any high-minded thinker on the left ever wants to lament the degradation of political discourse, they have only to look to Olbermann as Exhibit A.  In any case, his capacity to ignore real evil in the world, finding it only where someone disagrees with him ideologically, marks him as a profoundly silly and deeply unserious man.
