It's like getting rid of American and saying your nationality is white black or Hispanic
May Israelis describe themselves as Ashkenazi-Jews/Israelis, or Yemanites-Jews/Israelis, etc.
But the state recognizes jew and Arab in its official documentation. It's it does not recognize Israeli as the nationality. the use of jew and Arab in this manner is based on the conception of a Jewish race- a result of the historical development of Zionist ideology.
And just which documentation would that be?
You're just dead wrong here.
