It may be that my poor vision prevents me from following some complex
asrguments here, but in so far as I have made any sense of the argument
between Ken & Diana, it goes roughly like this:

John Doe: A

Richard Roe: Not A, A

John Doe:  A not B

Richard Roe: I said A not B not 

And sor forth.

Are either of you reading either each other or anyone else's posts?
