Some of what this guy talks about happen over 400 years ago. All races had salves.
But here is something important about us in American. Over 640,000 soldiers died or wounded to end slavery. A new party was found on the idea to end it. And another 390,000 died trying to keep it. 2,000,000 Union soldiers won the war. And one of our greatest presidents died over it.
See this pic, they where freemen. and willing to kill to stay they way.
80 years before the war there was free states. So for more then 200 years in this country there was people fighting slavery. Later they where called the Union army or, Republicans.
