No one is saying whiteness is a necessary condition to being Icelandic or Jewish. The point is that when Elon says “you have said the actual truth” to someone who claims Jews are oppressing white people, he isn’t thinking of Beta Israel or Yemenite Jews. He isn’t even thinking of Sephardic Jews. He is thinking of Ashkenazi Jews, who are white. He just doesn’t understand that. He very likely doesn’t even know non-white Jews exist… but the Jews who are white are often not considered to be white because they are Jewish. It is the othering of Jews we’re talking about.
