Determining how many people died as a direct result of armed conflict between Native Americans, and Europeans and their descendants, is difficult as accurate records were not always kept.[51] Various statistics have been developed concerning the devastation of the American Indian Wars on the peoples involved. One notable study by Gregory Michno used records dealing with figures "as a direct result of" engagements and concluded that "of the 21,586 total casualties tabulated in this survey, military personnel and civilians accounted for 6,596 (31%), while Indian casualties totaled about 14,990 (69%)." for the period of 1850–90. However, Michno says he "used the army's estimates in almost every case" & "the number of casualties in this study are inherently biased toward army estimations".[52]
According to the U.S. Bureau of the Census (1894), "The Indian wars under the government of the United States have been more than 40 in number. They have cost the lives of about 19,000 white men, women and children, including those killed in individual combats, and the lives of about 30,000 Indians."[53]
In God, Greed, and Genocide: The Holocaust Through the Centuries, Grenke quotes Chalk and Jonassohn with regards to the Cherokee Trail of Tears that "an act like the Cherokee deportation would almost certainly be considered an act of genocide today".[54] The Indian Removal Act of 1830 led to the Trail of Tears. About 17,000 Cherokees — along with approximately 2,000 black slaves owned by Cherokees — were removed from their homes.[55] The number of people who died as a result of the Trail of Tears has been variously estimated. American doctor and missionary Elizur Butler, who made the journey with one party, estimated 4,000 deaths.[56]
So, a total number over 200 years of several tens of thousands is reasonable for the territory covering the United States, noting that most of these were actually combat casualties in which Whites also were killed in substantial numbers. In no way would this been enough to cause a large decrease in the native American population. Btw, Andrew Jackson, the first Democrat Party president of the United States, was personally responsible for the Trail of Tears - the single greatest crime against North American Native Americans.
All this handwaving about millions of Indians killed in genocide does is create hot air which I think we have more than enough of already particularly from Leftists.
Actually, these figures are probably good since 1500 AD because prior to 200 years ago, Whites living in the current territory of the US were were almost entirely constrained to portions of the territory of the 13 original colonies, and not much of that for most of this period of time. There were less than 4 million people enumerated in the 1790 census. To imagine that these people making an existence for themselves in the relative wilderness had nothing to do but rove the North American continent butchering millions of defenseless Native Americans is laughable.
