Throughout our history, there has been a long list of those we've been conditioned to hate. The British, French, Spanish, Germans, Japanese, Russians, Communists, Northern Koreans, Vietnamese, Iranians, Taliban, and both northerners and southerners in America are some of the people we've been encouraged at various times to call enemies and to hate. The list is long, and as time passes, those we were assigned to hate we later were told should be removed from our hate list. The enemy is obviously hatred itself. Have empathy for your assigned enemy.
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 – let not the contemptible eunuchs tell us that they are equals before a court of morality!
I think that, in comparison, New Yorkers and Northerners are so guarded.
