Well, I addressed the argument directly. Can I help it if you can't handle the truth?
I believe that the Schindlers' publication of this book is motivated at least partially by money. They state that profits from the sale of this book will go to the foundation, but they do not use the usual formulation of "all profits" or "100% of the profits". That leads me to believe that they intend to keep some of the money for themselves. Furthermore, as it was previously mentioned on this thread, several members of the Schindler family are officers in this foundation. That means that the can pay themselves a salary out of the foundation's funds. That means that they would profit indirectly, rather than directly from the sale of this book. Finally, common experience shows that money corrupts. It is only natural to conclude that the Schindlers' could personally profit from this book sale, a possibility I believe you dismiss out of hand because of the sympathy you feel for them. Don't be a sucker.
