This is a repellent book, though of historical interest (which is why I've broached it). Even more repellent are some features of the abridged translation that I'm reading: despite some unconvincing disclaimers, it's pretty obvious that the publishers and editors are more-or-less endorsing Luther's anti-Semitic rantings.
I haven't felt this tainted by reading a book for a long time. In fact, I can't remember when I ever felt quite like this just about reading a book. Maybe reading a Gor novel, or something.
