No. Genocide is a historical process by which one faction of a population exterminates another. It is a specific social phenomenon which has objective characteristics that are necessary to function [1]

Also, genocide produces an imperative for other countries to intervene. As a result, warping the definition of genocide is a tool that imperialist nations use for invasion. In most cases, when the definition of genocide is warped in imperialist society, it is used to further imperialism and actual genocide.

There are obvious exceptions, e.g. the US denial of the early Holocaust. However, if the scientific method for identifying a genocide was used in the US given the evidence at the time, then one would correctly identified it as a genocide. The problem was that the US capital was heavily invested in Nazi Germany.

A strict adherence to the scientific method for identifying a genocide is the only way to prevent genocide denialism.
