But Nazis were not there for several generations, had not overcome several near extintions yet and they were already their own "breeding cave" "Lebensborn" project.
True enough, people forget that it was only for about twelve years that they were in power. But as you say, they already had started to breed new human races, though with very limited success, yet the ideology was there. Lebensborn is at last in theory not that far away from the idea of creating "Uruk-Hai".
Well that would be similar to Nazi/Daesh women as i supposed.
I could see female orcs as not being total slaves but also at the same full active collaborators..
