“His zeal in the cause of my race was far greater than mine - it was as the burning sun to my taper light - mine was bounded by time, his stretched away to the boundless shores of eternity. I could live for the slave, but he could die for him.”
"Brown, a white man who hated slavery so much that even his friend, the famed abolitionist and former slave Frederick Douglass, wished Brown would shut up about it every now and then." - Sarah Vowell
I don't think the people of the slave states will ever consider the subject of slavery in its true light till some other argument is resorted to other than moral persuasion.
