The last person who said the answer (and did a good job) never said if it was social or political. Its social.

Answer 2

It would have to be the lives lost, and the many other lives shattered by amputations and lost minds. Casualty figures have been revised upward. The overall population was about 31,000,000, not including about 4 million slaves. Of that total, half were women, which leaves some 15,000,000 men. There couldn't have been more than 5 million adult males. Out of those, some 750,000 died from wounds or disease, with over 1,000,000 afflicted (amputations, etc.) This represented almost 20% of the adult male population, and it was worse for the South (in proportion). 
The Battle of Gettysburg killed over 50,000 men in three days. Three years of the Korean war resulted in about 53,000 American dead. Ten years of the Vietnam War also resulted in about 53,000 dead. The Civil War was a holocaust.
