That's exactly why she made it on the radio, and eventually to Youtube. She made her interviewer sound like a genius by comparison.

No, I'm not being flippant, her mindless inanities have been brought to our attention so that those who are opposed to her can legitimize their positions as the only obvious, rational alternative, and so those who subscribe to any part of her views can be ridiculed and summarily dismissed as irrelevant. It happens on this board all the time, it's just done with a bit more subtlety because the target audience is somewhat more sophisticated than Mr Savage's.

As for the lady caller, she was probably legit, (yes, there are people that clueless) but it can't be ruled out she was a plant, either. It's an old propagandist's trick, if you want to get a controversial or unpalatable position accepted, trot out some flaming idiot who's against it for all the wrong reasons. There's probably a Latin term for it.
