I think the David Letterman argument is fine, however one must ask whether to highlight particular disputes at all is relevant as the entire document highlights nothing but contentious issues...however I beileve Bill Oreilly likes to be in contentious issues.

As to the specifics of why I erased it....you provided no dispute quotations taken from Bill Oreilly.  He had some zingers that nailed Dave hard what was chosen was the weakest of his points vs the strongest of lettermans...

Rewrite it.  Oreilly's comment about not calling people who blow up innocent women and children on his show as a devestating blow to Letterman and a clear clever and concise statement.
