Why in the U.S.A. are north Africans,Middle Easterners & Jews classified as "White" in the U.S.A. census?

The only peoples that may truly racially identify themselves as White are gentile White Europeans & all peoples of the world who are of pure gentile White European ancestry. I as well as most gentile White Europeans dont consider north Africans,Middle Easterners & Jews to be "White".
