Didn't we learn anything from Dan Rather? It didn't matter that the documents were fakes, What mattered was they supported what Dan knew in his heart to be the truth, and we can't be bothered with minor issues like authenticity.
Likewise, Frey is telling a story that The Oprah wants to believe is true, so if 95% is made up that's OK.
Facts are downright inconvient sometimes, so some of us (Dan and The Oprah) have learned that the truth can be flexible, as long as it is what we already know in our hearts to be true.
This whole story is sickening (no pun intended with respect to his vomiticiousness) -- the book is listed in the Non-Fiction rankings. It is a book of Fiction. It *does* make a difference.
And Frey himself is lame.
