>if a Nazi installation was a "concentration/extermination camp" or a "collection camp" I'm not sure if a "collection camp" is an accepted term, or a term related to Holocaust denial, but there is a fact-based distinction between concentration and extermination camps, and a "collection camp" sounds like it might mean a camp that was used to gather people to be sent on to the others. For example, "the Theresienstadt ghetto functioned in part as a transit center for Jews from Czechoslovakia, Germany and Austria on their way to extermination camps and other mass killing centers" Regarding massacres: "The term massacre, being a synonym of "butchery, carnage", is by nature hyperbolic or subjective, primarily used in partisan descriptions of events. There is no neutral definition of what constitutes a "massacre" although some authors using the term may lay down general "working definitions" of what they mean by the term" Things described as massacres seem to range from the killing of 3 people to a million.
