Then you would justify that it was the owners right to consider another human 'his property'. It worked for England only so much as it shifted the slave trade more to other countries. We had already been fighting the moral battle for years to no avail.
Well I should do the politically correct thing and say “Slavery was wrong” and totally ignore history.
But for the time and place of the preindustrial world then yes Slavery was justified. I personally believe that it would of ended by the 1880’s because of economics such as cotton from India and Bowel Weevils.
Civilization and the United States was built on slavery. I am not trying to make a living in 1840 Alabama so who am I to judge?
I can’t figure out a morality that would result in a war with 500,000 dead, many more injured. An entire section of the nation destroyed. Reconstruction and the KKK. and racial problems since then. I guess I am immoral to say that it is better to pay the slave owners and prevent all the above from happening.
Morality is a funny thing. A liberal would say it is immoral not to have free health care for everybody no matter the cost. A communist would say that capitalism is immoral.
You are saying that George Washington, Thomas Jefferson, and Robert E. Lee was immoral. I am saying they are not.
