Peter (fl. 1863) (also known as Gordon, or "Whipped Peter", or "Poor Peter") was an escaped American slave who was the subject of photographs documenting the extensive keloid scarring of his back from whippings received in slavery. The "scourged back" photo became one of the most widely circulated photos of the abolitionist movement during the American Civil War and remains one of the most notable photos of the 19th-century United States.
I don't disagree with your assessment of Trump and his goals, or at least what the goals of the people he's surrounded by are. However, I've been talking about how I believe most of his base pereceives his comments which is usually pretty different from what he's literally saying. His base hears what they want to hear in whatever he says and in this case I think that is "I don't need to force myself to confront an uncomfortable topic" not "slavery is good".
