Bill meant "Platonic dialogue" literally

Here's the definition: http://www.wordiq.com/definition/Dialogue The arguments below are real, but the characters and setting are fictional (barely so, they really are here, we just don't waste our time talking to them, since Bill and I know about their imperviousness to reason).

He was using "platonic dialogue" literally, and not as a sarcastic comment on the quality of the interlocutors. Sorry for any confusion, folks.
