Holocaust deniers also claim that most victims died due to diseases. The destruction and enslavement of natives did in fact cause their high mortality due to diseases.

There were also white towns that made money selling alcoholic beverages and drugs to native reservations. Usually long periods of starvation cause high rates of diabetes (amongst other symptoms) in a populace - today the lakota people have one of the highest percentage of diabetes per capita in the world.

The idea of not killing off natives was never present in any large capacity in the early united states.
