The problem is that because people in some parts of North Africa and/or the Middle East tend to have lighter shades of skin than people from various other parts of the world, race essentialists choose to classify them as "White" because they subjectively refuse to view these folks as "Black enough" or "Brown enough" to join the BIPOC club.
All the more reason why there needs to be a "MENA" option added to the U.S. Census forms.
