"It may not be PC, but on average human life improved in North America after Columbus"
Yes every European settler's human life improved. Unfortunately, the lives of those that were abused and killed by those settlers can't make that claim.
Believe me, I don't have an issue with history as it unfolded. I am not Indian, nor European. I am a mixture of Middle Eastern, Spaniard and American Indian. And I don't give a f*&k about any ancestry. What troubles me is the Eurocentric narrative of history of the American continent.
