I suppose the calls are screened and the show isn’t actually live. Otherwise, it would be interesting to watch Oprah’s face when a caller started to bring in quotations from Mein Kampf with the words, “I think Hitler had it right when he said...”.
Of course, if these loonies objected to the source of the quote, they could be hoist on their own petard. This is the type of attack Buckley used to use against moral relativism.
People actually know better when you put it in these terms.
