Delusions of grandeur, much? Ingraham believes that to be an effective family therapist you must listen to her show? And notice how after finding out the guest doesn't listen to talk radio Ingraham wants to dig up info on the guest so that she can personally "destroy her" with ad hominem attacks. Ingraham begins saying "she's a big liberal" - you can hear the dripping contempt she has for "liberals". The guest actually works with the conservative Heritage Foundation, but to the Manichean ego-maniac, if you don't listen to Lord Ingraham, Goddess of the AM you're a "liberal" and an idiot.
And this psycho is Bill O'Reilly's regular Friday guest host.
Edit - Commenting further, notice how reflexive it is for Ingraham to start looking to attack the guest's character. In the worldview of Ingraham and so many of her ideological cohorts, to disagree with them on something (in this case apparently that one must listen to AM radio) means that by definition there must be something wrong with your character. If they can find (or in many cases - fabricate) something wrong with a person's character then they don't have to bother considering why someone might disagree with them on an issue. It isn't so much about the person being attacked as it is about them finding someway to reduce cognitive dissonance for themselves; in short, a way of circumventing having to think.
Recall that this is exactly what happened to Glenn Greenwald for criticizing the hypocrisy of Malkin-sphere bloggers.
