"My point is that PBS fills a void that commercial programming does not. I don't see the opera Carmen or the ballet Swan Lake being shown on NBC."Apparently there is not enough demand for such programming, or some network would carry it. Public funding for this forces the majority of people who have no interest or desire for the programming to pay for it for the few who do. This is no different than if I got the government to force you to help pay my Direct TV bill every month.
The term "bully pulpit" stems from President Theodore Roosevelt's reference to the White House as a "bully pulpit," meaning a terrific platform from which to persuasively advocate an agenda. Roosevelt often used the word "bully" as an adjective meaning superb/wonderful. The Bully Pulpit features news, reasoned discourse, opinion and some humor.
