Oh, I don't know. I believe that "nazi" comes closer than the beauty Silvana Mangano. I say that not only because Cosima wasn't exactly easy on the eyes, but because she was much more rabidly anti-semitic than her husband. It's a wonder that mahler squeaked through at all, and I think that that's the point that K.R. was trying to make with his obvious exaggeration. Silly or not, I certainly found it entertaining.
