Scholars use the term "denial" to describe the views and methodology of Holocaust deniers in order to distinguish them from legitimate historical revisionists, who challenge orthodox interpretations of history using established historical methodologies. Holocaust deniers generally do not accept "denial" as an appropriate description of their activities and use the euphemism "revisionism" instead. The methodologies of Holocaust deniers are often based on a predetermined conclusion that ignores overwhelming historical evidence to the contrary. In some former Eastern Bloc countries, Holocaust deniers do not deny the mass murder of Jews, but deny the participation of their own nationals in the Holocaust. In 2019 the "Holocaust Remembrance Project Report" highlighted this form of denial which they described as "revisionism". They picked out Hungary, Poland, Croatia and Lithuania as the worst offenders. They also noted that Israel has supported many of the nationalist and revisionist governments mentioned in their report, rather than protesting such excessive revisionism.
