It only ever comes up in response to insults from ignorant and sanctimonious fools originating in socialist hellholes like New York.
My ancestors fought in the Revolution. Their grandchildren also fought in both sides of the Civil War. None of them owned slaves at any time (mostly German immigrants). They fought for their States and their homes.
I’ll be damned if I’m going to let their memory be insulted by Johnny-come-latelies like you.
It's time to update your calender, it's no longer the 1860's.
