Sorry, but Whoopi should have read the particulars of Nazi racial theory before expounding on the Shoah. If you don't bring the right intellectual equipment to the discussion, don't sit at the table. Applying an American racial framework to a German template is a form of low grade Holocaust minimalization. It ignores this genocide's uniqueness, springing from the only millenia-long hatred that is planetary and views its target as exercising superior, hidden conspiratorial power.
I hope she takes advantage of the free two weeks to go to Tennessee to teach a middle or high school class Maus, adding that the Nazis' Nuremberg Laws of 1935 copies American Jim Crow's codified racism after a team of Nazi lawyers visited the ABA in NY in 1934 to learn about American Jim Crow laws. I could introduce her to my grad school classmate who's the Assistant Editor of publications at the Holocaust Museum in Washington to help her do this.
The final lesson is, read before you talk...or at least listen to those who've already read before you do. If not, the result is inevitably: ready, fire, aim.....apologize.
