Excepting the shows that involved begging for listener money, there were inevitable left wing messages and political instruction in every program. The Alinsky weapon of RIDICULE was especially prominent during the Presidency of Dubya, during which they would mock and deride our President at all opportunities (some seemed ad lib and other attacks were clearly written.)
Aside from the fact that these fungi (talented, but definitely fungus) do not appreciate the First Amendment rights that let them perform anti-American activism "art", what really bugs me is that a portion of MY tax money goes to support leftist activism that I find so repellent.
Right-o! Garrison Keillor, Steve Smith ("Red Green"), Jim Henson and many others became multimillionaires from NPR/PBS. Sesame Street royalties could easily pay for all of NPR-PBS with no other inputs. It's just a large kick-back scheme for leftist politicians.
