Do you not agree that there are non-plague related reasons the natives in NA weren't equipped to resist colonization.
From a quick Google search, so they may not be super accurate, but populations in 1600:
China: 231-250 million
India: 100 million
Africa: 50 million
North America: ~100 million (before plague)
Also, the English and the like had been trying to colonize North America for at least 150 years, and had failed. The Vikings had been trying for 500 years.
