One of the many things that bothers me about white supremacists is their revisionist history of the Civil War. "Ol' Bobby Lee" was a gentleman and wasn't "that bad" on slavery. Well, 160 years ago TODAY the retreating Confederate Army kidnapped over 1000 Black people in PA and MD and took them to Virginia for enslavement. Few know about this, but it was a war crime on top of the tragedy of Gettysburg.
