I don't remember her ever being called out over an interview like this before. People know that when they go on her show, they're going to get softball questions, which is why they do it. The audience knows this as well. I quit watching her regular show a long time before it stopped airing. The most recent interview that I saw besides H&M was one Lisa Marie Presley had done some time after Michael Jackson died. I don't think she was telling the truth about the marriage, but I do think she may have believed her own BS. However, no one called her out and I don't recall a lot of attention placed on the interview in general at the time.
You always got this feeling that Oprah was one of those crapsaccharine people-- sweet and sparkly on the surface, with something nasty lurking underneath, but you couldn't quite put your finger on it. So you kind of went on about things and didn't think about it. Then you'd hear things like her giving away brand new cars that she didn't pay for and the recipients got stuck with thousands in taxes. The girls school fiasco in Africa. The idiots she spawned-- Ellen, Dr. Oz, Dr. Phil. OWN is basically UWN-- the Un-Watchable Network. Things like that. The saccharine coating is slipping off. Then the H&M interview and it's right there in your face, stink and all.
