The reasons I did not give "Think" a 5 Star rating, despite its overall excellence, are twofold: 1) Many author interviews are the same as those done by Terri Gross, usually within the same week, on "Fresh Air" from WBAI in Philadelphia. 2) The other reason is that the producers are unwilling to have guests on who are edgy, who challenge the status quo in regard to Western foreign policy, who openly criticize neo Conservative ideology, US support for Zionism or the narrative Western audiences have been given in regard to Syria, for example.
I blame these omissions not on the hosts such as the very thoughtful and intelligent Krys Boyd or her equally excellent substitutes, Lauren Silverman and recently, John McCaa, but on the cowardice and/or biases of "Think"'s producers who are probably frightened of offending their major donors and thus, losing much needed money and/or, they, too, are unwilling to put on the air a person who challenges their own biases.
I continue to listen to NPR and watch PBS, including, "Think" because it is a very good show. I continue to financially support KERA but, unfortunately, I cannot afford to contribute on a level that will get my voice heard.
If more small donors contributed, we could drown out the conventional, mainstream views of the huge donors and, en masse, demand genuinely unbiased news from our public stations.
