Only Christianity? none of the other religions? It's funny pushing religion on a Thomas Payne post since he rejected religion as corrupt and irrational.
The experiment has only been run once, and it was mostly a white, Christian project. Payne's personal values doesn't change the facts of the experiment. If we could go back in time and witness the invention of the Enlightenment, political Liberalism, and Industrialization for other (race, religion) pairs, I'd love to do it. Maybe we can, as a proxy, look across the world at how different (race, religion) pairs have adopted liberal values to see if there are any patterns.
