A number of replies come to mind but Alex has worked himself up into an attitude where the conversation is not worth pursuing. I'd rather break it off and remain on good terms than say anything that would be cause for harsh words among friends.

If we were face to face and could see the real reaction our words were having on each othe, could gauge the depth of feeling, and could feel the spirit of the debate then I would forge ahead.

Thank you for your comments, Alex, Wolfgang, Susan, and all.
