Slavery fanactics, you must mean the yankees who bought them in Africa. Millions of yankees made profits by venturing capital in the trade. They were so fanatic about slavery they sailed the oceans to procur their human cargo, and lusted so much after profits they brutalized them in holds barely large enough for them to sit upright, starving many, and tossing hundreds of thousands overboard as it suited them. Entire cargoes of slaves were tossed overboard, still in chains to drown or be eaten by sharks to prevent the yankees from being arrested for slave trading after 1808.
Post your proof of your slur against the Chief Justice, otherwise retract it. The justice defended Rev. Gruber against charges of inciting a slave rebellion, as well as freeing the slaves he inherited, providing for them until their deaths in old-age.
I think Dred Scott is all the proof I need. Good for Taney in his personal affairs, but his Dred Scott ruling is right in line with the American South's hardening idea of slaves as two legged property, the absolute ownership of which was not to be restricted.
I'm calling BS on this one. Millions? The entire free white population of the northern states in 1800 was barely over 2 million.
