Yes O'Reilly is a pontificating coward! He won't face anyone who he can't handle. He fancies himself as the superior teacher of all those childish misguided progressives! So he is afraid to face a real fighter!
No toe-to-toe action between O'Brien and Brock, unless maybe Davy'll call him up some day on his radio show.
Be careful that he doesn't send Zell Miller though to give Brock a "caning" a' la Rep. Charles Sumner in the 1840's.
