Your foreknowledge is superior to mine. I am merely filling in
  my gaps in knowledge as we go along to supplement my existing
  knowledge.

  Since you came prepared and I did not, I will shut up now as my
  contribution is invalidated.

  There.   You win. I don't know what you won, because I wasn't
  fighting, but, you win regardless.   But, when you're ready for
  a human discussion about history, I'll be around.
