Gordon, you have an enormous set of cojones! 😱 I could never do that!
I remember a bit more of the conversation. About the Lord's supper, I quoted Jesus ' command "This do in remembrance of me". The bloke said "And who was he talking to?" That's when I said what I said above. He made a beeline for the gate and left his wife holding the bag. The remaining dribs and drabs of conversation were with her.
So, yes, they are not the confident debaters they once were, in my recent experience.
