I would like to explore the frontiers of what you're willing not to dismiss out of hand. Can I interest you in a story about a secret blood cult John Podesta runs? How about the Lizard People?
I don't believe lizard people are real.
In less than 2 minutes of googling and reading you can find a comprehensive answer to all your questions, but instead you put forward a leading statement like "it was an interesting email that was uncovered."
It genuinely was not. It's not interesting, it's mundane.
