According to books I've read, Germanic/Jewish marriages were already happening in at least the mid to late 1700s. When I say Germanic, I include not just Germany, but Austria, Hungary and Switzerland.
Then again, Hitler considered a person non-Jewish if a person had no practicing Jew among that person's grandparents. He never looked at the ethnicity of a person's great grandparents. What's more is most, if not all of his top aides were 1/4 Jew, and conferred honors on Jewish officers who were 1/4 - almost full blooded Jew. Hitler and Himmler, and who knows how many others among the top aides, decided who was Jew and who was not according to their own convenience.
I've studied Hitler and many of his aides, mostly because my mother grew up under his regime in Germany, and they were all very sick, sick men, as are all dictators, and most of the Germans hated them.
If a ruler is loved by the population he rules, he doesn't have to resort to dictatorship, he can rule by popular vote. Hitler NEVER had more than a 40% vote from the population, and he only got that because, by that time, the German people were so terribly desperate, and he was telling the biggest lies. He knew he was hated by the majority of the German population, that's why he took over the government by force.
I'm sorry, guys. I know too much of how the Germans themselves suffered under him, from 1933 on. I've heard too many of my mother's and her families' stories, on top of all the research I've done. Hitler and his Nazis should NEVER be equated with the general German population.
I'm out of this discussion. If you have answers to any of my questions you can contact me privately.
Most Sincerely,
