I didn’t realize this was up for debate. I was taught in the 90s that smallpox (and many other communicable diseases) came over with Columbus and other 15th century colonists, causing devastation among countless communities which had no immunity.
The word they used was decimated, but that is only reducing the population by 10%. Wikipedia quotes a source that said up to 90% of populations were wiped out.

Yeah, I guess I had gotten someone’s weird rant in my head.
