What one person thinks is rude another doesn't.   Regardless of that, Joe and his wife are intelligent people and are not one sided.   He will give you an opportunity to state your point.   They just don't want you trying to dish out any nonsense or baseless statements as fact.   They want facts and where you aquired your facts.    They will take calls from both points of view unlike other talk shows.   If you listen to enough talk shows that right wing and left wing, you will see who accepts various points of view and who does not.
