I once had a discussion with a Southern Scholar of the Civil War.
BA, PHD, something that took years and a dissertation.
The topic came up and I said “you cannot deny that it was about sla ….”
“NO! I know what you were going to say and you are wrong. I ought to know, I wrote my dissertation on that very topic!”
“Okay but see, it’s right here in the first sentence of *this* state’s secession papers. They wrote this!”
“Obviously you have no understanding of history.”
