Holocausts  A deluge of words was written on this topic. Hundreds of facets of this issue can be argued, but no amount of words can obscure the glacial reality of the fact that among the countless atrocities of the last centuries, by far the greatest were the genocide of the native Americans (magnitude of this holocaust is estimated by David Stannard in his American Holocaust, 1992, pp. 74-75, p.151) to be 100 million people for the hemisphere and 18 million for the area north of Mexico), deaths associated with the slavery trade  (estimated to be 28 million people, cf., Stannard, p. 151) , and the holocaust of the Jewish people (estimated to be 6 million people). According to 1909 Census, the number of Cherokees was 369,035, Navajo 225,298, Sioux 107,321, Apache 53,330,  Cheyenne 11,809 and Comanche 11,437. In the 1910, the total population of North American Indians was about 400,000, down from about 18 -19 million in 1492 http://www.visualstatistics.net/east-west/genocide/genocide.htm
