I would imagine it talks about how the Khazers were of Magyar stock (Hungarian) and ruled the northern Caucasus from the age of classical antiquity, to the dawn of the middle ages. They had formed a bulwark separating the great eastern powers of Byzantium and the Arabs, but as conflict arises between the two, Khazaria was stuck between the Islamic faith and Christianity, so instead of subjugating into either of the two they converted to Judaism. The Mongolians finished them off but their diaspora assimilated into western countries, (especially Poland) becoming today what we call Ashkenazi Jews. The entire revisionism of this is that they are not real Judeans. People want to make gay conspiracies from it, and try to point out Rev 3 9. Its complete cope, they have no parallel to the bible. Judea was a multicultural nation. So in reality the orient question is what makes someone a Jew? Is it by faith? Is it blood? Maybe both.
