This is how you know an adult is unstable. The constant capped LOL when having a discussion. You are so flabbergasted bc they are so wrong and you are so right. Grow up and make your point.
I took his class, too, and even though I really liked Dr. T. Harry Williams it's just self-serving claptrap to declare him the "world's leading authority on the Civil War." Williams had his own biases. For my money and that of many others, James McPherson, for example, is far more thorough and enlightened.
Who said Rex was an adult. Probably a millennial who feels guilty because his dad works hard an makes lots of money.
Choose your own authority if you want but at the time T Harry was recognized by his peers as the leading authority.
