During the colonization of the African and American continent, many crimes against humanity have been committed (murder, expulsion of people, deportation, forced labor, slavery...). About all this is said little or nothing. Many European countries have participated in this and have literally destroyed many people, especially on the American continent, and have never publicly acknowledged their crimes. Communion of Aztec culture and the destruction of the Inca civilization, forcing African tribes to work in mines (the most brutal example is the Congo) the biological attack that occurred in North America against the alliance of the tribe of the Great Lakes during the time of the chief Pontiac does not learn and is not mentioned in the schools? Is it considered that these victims are less valuable and do not deserve to be spoken about or that Victims were needed to create a "better and more civilized world"?
