Books that talk about the truths behind historical events away from the sanitization of the status quo are wonderful. Using that concept to push outright lies and twisted facts so you can sell a book is NOT.

I don't care what narrative an author is trying to push: writing falsehood as actual history just to sell books with the wave of interest over an interesting topic isn't ethical. It erodes the entire fact that we love to study and discuss history not just for entertainment but preservation. Zinn is not preservation but a rewriter of truth for money.

I wouldn't accept this kind of shady misdirection and lack of proper citation from anyone, whether Zinn, Cambridge or Sesame Street and neither should anyone else.
