@boagie,
I have a bit of a problem with the above. The SS killed roughly 15 million people, of whom 3 million were catholic Poles and over 5 million were Russian POWs, most of whom were Russian Orthodox. While the Jewish Holocaust was the most comprehensive effort at an extermination program (i.e. 75% of all European Jews and 90% of all Polish Jews were killed), they overall were only a relative majority (i.e. not absolute majority) of the total noncombatant victims of the Nazi extermination programs.
Furthermore, someone was defined as Jewish and subject to the same persecution (i.e. death camps) if they had more than one Jewish grandparent,
even if they were worshipping Christians. The Holocaust and Hitler's policies were NOT because of any religious priority. Like the Spanish Inquisition, the issue was about
racial "Jewry" and not Jewish religion.
The Nazi rhetoric was very mixed on the subject of religious worship, but they were very anti-Catholic, and many of them (especially mystical people like Heinrich Himmler) were very suspicious about Christianity in general. Naziism had self-consciously strong pagan overtones, and it just can't be argued that Jesus had much to do with their policies.
Furthermore, irrespective of Hitler's quotes and beliefs, the planning and execution of the Nazi racial programs, including their camps and ghettos and transportation systems and censuses, etc, happened far beyond even Hitler's own penchant for micromanagement. Bar none the architects of the Holocaust were Heinrich Himmler and Reinhard Heydrich (at least until his assassination in 1942). At a local level it was the governers general in occupied territories (like Hans Frank) and the
Einsatzgruppen (in the occupied USSR) who carried out their own interpretation of the racial policy. And there's essentially no evidence that I know of that there was any kind of Christian motivation, except perhaps among the locals whom the SS employed to round up Jews for them.
Most of the rhetoric had to do with the threat the Jewish "race" posed towards Germany -- and it was never spoken of in Christian terms. And again, if you do some reading about Nazi mysticism and occultism (there are wikipedia articles about this), you'll find that there was a good amount of rejection of Christianity among the Nazis.
Of course the main reason that the Holocaust was self-perpetuating (despite overall being a huge resource drain) was that it provided the Nazis with slave labor. And while this was not ideological per se, the ideology in large part became a rationalization for the Nazi need for slave labor to support a total war. The Holocaust didn't really get going until Operation Barbarossa, i.e. when the Nazis invaded the Soviet Union in the summer of 1941, and that's with good reason -- they didn't have the slave labor needs until they committed themselves to that hopeless war.
