Gee, all these stereotypes about how public radio listeners are supposed to be. And what it airs. Do you/have you even listened? I doubt it. The tip-off: A general dismissal of public radio (usually mislabeled as "NPR") for liberal bias without any specifics. When actual public radio listeners see "bias," they get very specific. If you don't think so, check out the comments on the NPR ombudsman's page. If you want to talk about public radio's "liberal bias:" (1) Don't say "NPR" when you mean WNYC (i.e., Brian Lehrer, Leonard Lopate, etc), PRI (i.e., The Takeaway, The World, etc.) or APM (i.e., Marketplace, etc). and (2) And listen and find something you considered biased and report it.
Dittoheads don't feel the need to listen to public radio ("NPR) to complain about it. Rush has told them it's bad, so why bother to listen and decide for themselves.
When hosts are so much alike, one does not need a broad brush to cover them. Maybe you haven't listened to Curtis and Kuby; only the subway vigilante does right-wing schtick. Mike Gallagher is as nasty and incendiary and Rush, Beck or any of them.
Bloomberg does business news. If y'all want to limit the definition of talk radio to right-wing, political call-in shows, you can't turn around and compare Bloomberg to general news programs like Morning Edition or All Things Considered - or even Newsradio 880 and 1010 WINS. Besides, Bloomberg is only available on the air in three markets.
When any content is geared to smart people, dummies hate it.
