Slavery was widely accepted throughout the world prior to the Eighteenth Century. It was in 1776 that the British High Court ruled that “slaves cannot breath English air, for the moment that they do, they are free men.” Some historians claim that it was this action, and its implications for England’s colonies, that lead the Southern colonies to find common cause with mercantile New England. (New York was notably tepid in embracing the Revolution.) In other words, the American Revolution had as much to do with perserving slavery as the principles of representative government.
It would be interesting to have a reasonable, objective discussion on the issue of slavery’s affect on the US, but without the hyperbole and agenda driven absurdity of the living confederacy. So, it’s not going to happen soon...
