This is ridiculous. I think a man of faith has the right to question the religious validity of a position such as the 'pope'. If he finds the concept in contrast to biblical guidlines, he should be able to voice those concerns. Talk radio is all about discussion (which involves opinions of various inclinations). Just because he felt that the pope fell short of his ideas of God's will does not make him right, wrong, or even mildly offensive. If the station wanted to have a favorable rehash of popular opinion, they should have had a catholic minister hosting the show.
