"Can you describe the nature of the unrealness of these bills, as its own thing and not as the absence of something else?"

Just thought the dissection of that particular "weasel word" might help someone out there at some point.

"Brandy made in Germany isn't "real" cognac. The nature of the unrealness is that it was made in Germany and not the cognac region of France."

You may disagree but my point here is, right or wrong, you can always describe the nature of the unrealness, unless its being used as a cheap, underhanded rhetorical device.
