Slavery is not new. The Egyptian pyramids weren’t built with union labor after all. Unlike other places around the world, this Country fought a war to end it. From some numbers I’ve seen if it was fought with today’s population there’d be 6.2 million dead. Possible understatement of the year: that’s a lot of dead people.
Again, the war was NOT fought to end slavery. It was fought to stop states from seceeding and to force them into the union.
