I do not understand Yiddish therefore I do not understand who ‘Sephardic’ are. Sometimes it refers only to the Jews from the Iberian Peninsula and sometimes the Jews from the Middle East are also known as ‘Sephardic’ and at other times as ‘Mizrahi’. The Jews from the Arab countries are Arab Jews but the white Jews do not want to call them that. Please just refer to them as:
European Jews
Middle Eastern Jews
Iberian Jews
East Asia Jews
and there will be no misunderstanding.
