One of the jokes of the Israeli enthostate is how loosely it is applied. Afrikaner Protestants can convert to Judaism in order to gain citizenship, while Beta Israelis and Safardic Jews are subject to abuse and discrimination almost as harsh as any Arab native.
But then so much of the Israeli claim to diversity boils down to “we have every kind of European”.
Describing China as “majority Han” means about as much as describing Europe as “majority White”.
