I think the Ashkenazi and Sephardic Jewish races are social constructs created by the Kike religion
I do not call it the Jewish religion but the Kike religion because I deny their claim of having a higher percent of Judean ancestry than the Syrian so called Palestinians
I also deny the Kike claim of having a religious tradition passed down orally from the Old Testament Moses who would be like a distant cousin to Judah's descendants so do not call them Jews for that reason either
When they talk about Moses they often mean Moses Maimonides not Old Testament Moses
I think before Christianity many of the descendants of Israel already mated with descandents of Esau and it is hard to distinguish them all as two seperate groups
I would be more concerned about the ideology
One group made a book of excuses of how and why to not obey Moses law and of how and why to hate outsiders
The other group followed Christ's teaching of loving your neighbor but where love is not meant in the sense proclaimed by "liberal" churches
