It is the 150th anniversary of the War To End Slavery in the United States.
.
I wonder if in 150 years people will be as blase about Germans dressing up in World War II outfits.

ps: It was about States Rights -but only if you define that as the States Right to have Slaves - since that was the proximate and only real cause. Every other State issue had been resolved without a war both before and since. (The Whiskey Rebellin wasn't between states but between reginal moon-shiners; but points for good try.)
