It wasn't just Jews which were targeted...
TARGETED GROUPS
The Nazis defined Jews as a “race.” Regarding the Jewish religion as irrelevant, the Nazis attributed a wide variety of negative stereotypes about Jews and “Jewish” behavior to an unchanging biologically determined heritage that drove the “Jewish race,” like other races, to struggle to survive by expansion at the expense of other races.
While it classified Jews as the priority “enemy,” the Nazi ideological concept of race targeted other groups for persecution, imprisonment, and annihilation, including Roma (Gypsies), people with disabilities, Poles, Soviet prisoners of war, and Afro-Germans. The Nazis also identified political dissidents, Jehovah’s Witnesses, homosexuals, and so-called asocials as enemies and security risks either because they consciously opposed the Nazi regime or some aspect of their behavior did not fit Nazi perceptions of social norms. They sought to eliminate domestic non-conformists and so-called racial threats through a perpetual self-purge of German society.
The Nazis believed that superior races had not just the right but the obligation to subdue and even exterminate inferior ones. They believed that this struggle of races was consistent with the law of nature. The Nazis pursued a strategic vision of a dominant German race ruling subject peoples, especially the Slavs and the so-called Asiatics (by which they meant the peoples of Soviet Central Asia and the Muslim populations of the Caucasus region), whom they judged to be innately inferior. For purposes of propaganda, the Nazis often framed this strategic vision in terms of a crusade to save western civilization from these “eastern” or “Asiatic” barbarians and their Jewish leaders and organizers.
