My sister-in-law used to say the same thing. She didn’t get his humor. She thought he was an arrogant braggart. Listening to him for only short bursts and giving up too soon can leave a person with that impression.
I have listened to him for long stretches of time over many years and I think I have a pretty fair understanding of what’s beneath the surface. The guy is classy when dealing with callers, shrewd in his understanding of the enemies of this country (both foreign and domestic) and he is a lot more humble than his humor would suggest. He always says that one must listen to his radio program consistently for several weeks to understand him and I believe that is true.
Ditto that!
