You know, when a proper and sophisticated Conservative Southern Aristocrat Gentleman beat an abolitionist with a cane because he dared called slavery evil and said we should end it. Because, you know, it was evil and Africans and their ancestors are humans who deserve to be treated as such, which this Fine Man and his colleagues took issue with. You know, typical Southern Conservative values.
But yes, Jackson also had to be held back from beating his would-be assassin to death with his old man cane.
