Re NJP Platform point number 4. The practical implementation of this has been troubling me. For any history buffs here, how did Jews become so race mixed with white people that most of them are physically indistinguishable?
Given that Jews change their names, how could a NS government keep track of all of them?
As they lost their homeland to Greek, Roman colonialism and influences (you can read about their struggles to maintain their identity as Hellenism was spreading etc.), only for Byzantium and later Arabs to deliver a deathblow and obliterate every semblance of a Jewish state, they started to migrate to Europe and settle there. For Jews, it was nothing new or special - their holy book already documented similar troubles through Egypt and Babylon, and it was often considered a divine punishment for failing at monotheism and adopting idolatry, something that Jews did again and again as they copied their neighbors instead of remaining the pure "nation under God" they were supposed to be.
In Europe, not everything went well, as we already know, and pogroms, expulsions, mass conversions were rather common. Sometimes, they re-migrated back towards the Middle East, and ended up in the much more tolerant Ottoman Empire, which practiced a much tamer version of Islam compared to the Arab first wave of Muslim expansion, which was quite anti-Semitic and had open tribal conflicts with Jews in Medina and other places in the Arab Peninsula.
When populations migrate and settle over centuries, there is no avoiding of mixing up, and there was already lots of mixing due to the Greek, Roman, Persian and Byzantium empires which often held many Semitic and North African possessions and tribes.
Keeping track of "all of them" will be largely impractical and probably impossible. There are (non-final) solutions to this sort of stuff but not the place for such discussions and it would derail the thread.
Fully recommend reading both Arab and Jewish history, it's absolutely fascinating and quite the journey. Obviously, you shouldn't really consider the Jews that rebelled against Rome and bravely sacrificed to maintain a homeland the same as those today, and same goes for Arabs, the current year Arabs have almost nothing to do with the patriarchal, simple yet noble and courageous Arabs that swept over Byzantium and Persia. These eras of stoicism and bravery are almost always really short, i.e. until you hit the riches and plunder them, and then corruption and decay sets in.
