Even if I steelman this attempt at an argument to its fullest, "exaggerated" doesn't mean "didn't happen"--if you go actually read the article that Wikipedia page cites, von Vacano does not claim that it's false--and we have other contemporary accounts of the Spanish acts of genocide on Hispaniola alone.
Somewhere in the mid hundreds-of-thousands to a million Taino, depending on which ends of the estimate make sense to you, lived on Hispaniola when the Spanish showed up.
By 1650, they were gone.
I wonder what happened? Maybe it was ghosts.
