According to the best estimates the Americas were populated by Asians who came over a land bridge between Siberia and Alaska 10,000 - 12,000 years ago. for his drivel to even have a chance of being true, that would have to mean that those diseases evolved in the last 10-12k years. Extremely unlikely. Does anyone think that stone age man in Europe and Asia was disease free?
Then there is the total lack of verification of the diseases tolls upon the natives. Nothing factual at all just speculation. this kind of drivel is uncritically accepted by morons which is some regard why there are Democrats in government today - representing the credulous morons in the country.
