That is just how people identify as, Tunisians look nothing like middle eastern, they have a Maghrebi look and so do other Maghrebis, I know you want to be an Arab so bad, but the real Arabs don’t like you, no need to be something you aren’t when you can be proud of your origins. Tunisia is a country with a long history, no need for the Arabs, the French or who ever else to overwrite who we are.
