“In fact, never before you posted your comment have I associated the term Mizrachi with kipa sruga Jews.”
Then you’re very out-of-touch and prone to having many a confusing conversation with Israelis.
“Only during th reshonim time is where the Jews migrated to ashkenaz countries …..I believe”
Let’s just say this were true, so what? Wouldn’t you want your migration to have happened later rather than earlier if you were claiming your mesora was closer to what was done in Eretz Yisroel?
Also, there’s no evidence of Jews living in Carthaginian Spain. The communities were probably not there until at least Roman times (maybe you weren’t claiming otherwise; it wasn’t clear). The reason we call places like Persia “Sphardic” (which means Spanish) is because many Spanish communities fled to places like that after the expulsion of 1492. None of this has any bearing of mesora authenticity; I’m not getting involved with that. The point is, Jews living under Cyrus the great were not “Sphardim.” There’s no connection between the ancient Persian exile and the 20th century Persian communities.
