What contradictory nonsense. Clearly the world (particularly the New World) is better off for the introduction of Western Civilization. The left as usual has focused exclusively on the warts of Western Civ while ignoring those of the rest of the world. They judge Western Civ by contempory liberal standards, while deeming criticism of other cultures as racist. What they ignore is that slavery and persecution have been the norm in every society in the world until a bunch of dead white guys invented freedom and human rights.
Now, Columbuss culture did still have absolute monarchs, repressive churches, and slavery; the changes that would eliminate many of these conditions were also still hundreds of years away. Unfortunately, the two worlds were more alike than different. I do believe that this would not have changed in the new world on its own, and we all know that it did change for the better in the Old World.
