History has different yardsticks for the cruelty of the Northerners and the cruelty of the Southerners in the Civil War. A slave-owner who through cunning and violence shackles a slave in chains, and a slave who through cunning or violence breaks the chains โ let not the contemptible eunuchs tell us that they are equals before a court of morality!
