Well, I listened to what she said, and her first statement was that all the book, Maus expresses what can happen in any society by any people group. She then expressed that the Jews who were being killed were mostly white skinned, just like the Germans who were killing them. So...skin color had nothing to do with the genocide. She also stated that it was an ethnic genocide, not a race, which is technically correct. Race is a false construct.
She did not deny that gypsies, Christians, homosexuals, people with disabilities, etc., were also killed. But, that wasn't her point. (That was the misdirection of the others on the program). Her point was that all humans can learn from the book, Maus, that humanity is capable of great atrocities.
Finally, your lack of knowing my knowledge of history is forgiven.
