It is really not difficult to grasp the fact that the Nazis treated German and Austrian Jews with a degree of circumspection that was utterly absent in Poland and the occupied Soviet Union. That's because whereas the aim was a total solution, in practice separating German and Austrian Jews from the 'Aryan' population was always going to be tough due to the degree of intermarriage and the existence of mixed-race (by Nazi standards) offspring, as well as the fact that contrary to antisemitic propaganda since WWI, there were quite a few war veterans among German and Austrian Jews. This caused even hardened Nazi ideologues to complain when German Jews with Iron Crosses were deported to Minsk in the autum of 1941.
As a result of the complaints, protests and appeals from different factions of the regime, together with the Nazis' basic confusion over how to draw the line, the implementation of the Final Solution was an inevitable political compromise. It's really not hard to find examples of compromise in political history; the question is why you think that the Third Reich was somehow above politics and why the Final Solution would be immune to political pressures. It certainly wasn't in the satellite states since the Nazis had to rely on diplomacy to get their victims, and quite a few satellite states refused. It wasn't free of politics in Poland or the Baltic States, since some Nazis wanted to keep some Jews alive for labour whereas other Nazis wanted to kill 'em all, as is very clearly spelled out in the Jaeger report.
And it wasn't free of politics in Germany, since the Nazi leadership made a number of calculations about what it could get away with and whether there would be opposition, protest or complaint. The German public didn't especially like the introduction of the yellow star and this caused a certain unrest; so the Nazis decided not to publicise the deportations. They covered it up. There were no stories in the Nazi press about the deportation of German Jews. That was a political decision since the press was centrally controlled. That's just an example of how this process was going to be subjected to a dozen different influences when it came time to implement the Final Solution.
1. Mischlinge were exempted from deportation unless they belonged to the Jewish religious community, in which case they were deported
2. Elderly German and Austrian Jews and WWI veterans with decorations went to Theresienstadt, where they were meant to be left to die 'peacefully', as Himmler stated to Kaltenbrunner in early 1943. Quite a few were deported onwards from Theresienstadt, but this was not done consistently. The decision to set up Theresienstadt as an old people's ghetto was the result of complaints from the east when elderly German Jews turned up and caused Nazi leaders in the east to get upset. It also proved useful for PR reasons later since Theresienstadt became a Potemkin village.
3. German Jews working in armaments - who due to wartime labour shortages came to quite a sizeable minority of the total community - were exempted from deportation in October 1941 after pressure from OKW; Hitler decided in September 1942 that they would be replaced by Poles and Russians, and this was then carried out in February-March 1943, which is why that operation is called the 'factory action'.
4. Jews in mixed marriages were also exempted from deportation at Wannsee.
5. Everyone else was deported in 1941-2.
That was the shape of the Final Solution from early 1942. This is perfectly well documented; deportation = being subjected to the Final Solution; exemption = not being subjected to the Final Solution. Everyone other than you and Clayton seems to be able to get this perfectly well.
To the extent that there is any argument here at all, it is over what the Final Solution meant after Wannsee. Deniers handwave and say 'resettlement'. Everyone else says that this meant death, either quickly for unfit Jews or more slowly for able-bodied Jews (as spelled out in Wannsee).
An exemption from the Final Solution cannot be used to call into question what the Final Solution meant. It's utterly illogical to make such a claim, but surprise, that's precisely what you're doing.
You're incidentally wrong to say that divorce was rare for the group of mixed marriages. Considerable pressure was brought to bear on the 'Aryan' spouses; so that quite a few decided that they would abandon their husbands or wives and leave them to their fate. That happened to one well known diarist, Lili Jahn. Her husband divorced her and she was deported and did not come back. Whereas Viktor Klemperer's German wife stood by him right to the end of the war.
Evidently the Nazis' sense of what they could achieve was different to yours. They didn't bother with many exemptions in the occupied territories; in the occupied Soviet Union, Russian wives of Jewish husbands were simply thrown into the temporary ghettos and many petitioned to be allowed to divorce them, which was basically ignored since it was an administrative hassle for the simplified occupation administration. Most of the satellite states also exempted mixed-marriages and Mischlinge, following the German model. Some also exempted converts, which was very prominently not something that the Nazis did in Germany or in the directly occupied territories.
I'm really at a loss as to where this line of unreasoning gets you. The conventionally accepted history states that ca. 200,000 German and Austrian Jews died after being deported from Germany and Austria, in a wide variety of locations. They were shot in Kaunas, in Riga, in Minsk, gassed in Maly Trostinets, Chelmno, Belzec, Sobibor, Treblinka and Auschwitz; they died of maltreatment in Majdanek and countless ghettos and labour camps, including in Theresienstadt.
There were survivors from those deportations because the Final Solution meant, from Wannsee onwards, that able-bodied Jews would be used for slave labour. That's why the 'factory action' sent more than 15,000 Berlin Jews to Auschwitz in February-March 1943, where they were selected on arrival, with a high proportion being sent to the gas chambers while a considerable minority went to Monowitz to slave there, whereupon many more died.
That's the accepted history. You're not going to get very far challenging the accepted history if you bring up points that are irrelevant to the issue of how 200,000 German and Austrian Jews actually died. The gambit of 'this Jew survived, therefore none of the other Jews died' is as silly now as when the first denier repeated this fundamental strawman of the history.
Sure, you can point to some historians and some commentators who think that the Rosenstrasse protest 'saved' the Jewish husbands in mixed marriages from extermination. But Stolzfus is wrong. The memorial is a feelgood spin on an especially grim story of man's inhumanity to man. Wolf Gruner demolished the Rosenstrasse myth about 7-8 years ago and his work is convincing. That's why Evans and Friedlander agree with him.
But please, keep digging. Your know-nothingism and utter ignorance of the history is most entertaining.
