My point is, if they choose to call our situation a double identity, then let it be, as long as the person is aware of the fact that his identity consists of both equally, then to hell with what others call it.

I too believe that nationalities, religion, places you live play a role, but not in creating your identity as much as in shaping up your personality, enriching your background and reflecting on your mentality. To me identity consists of: 1. your ethnic & cultural heritage, 2. the blood that runs in your veins. Therefore holding a passport of a certain country alone doesn’t mean your nationality became part of your identity, it just means it’s a document that legally identifies you, and this is different. Also living in a place for a very short period of your life or for work means this place is nothing but a station that you know you’ll leave sooner or later; so to me that doesn’t count either.
I was born in Kuwait and lived there for 13 years, but I don’t consider it part of my identity. My identity is my blood, my tradition that I got from my ancestors and from the country I grew roots in, and that doesn’t change wherever I go.

What I’m trying to say is, when asked ‘where are you from’ Adam will definitely say: I’m half Tunisian, half Palestinian. Or, I’m Tunisian, of a Palestinian mother. Jordan means nothing to him (in terms of identity) since he never lived there, nor does he hold its passport (again even if he had its passport but didn’t live there it’s not part of his identity). And whatever another passport he might hold one day, it will be part of his identity IF he lived there and became part of society in each and every way. And then he’ll answer: I’m a ______ national, of Tunisian & Palestinian origins.

What I would say is that there is no such thing as a ‘double identity’, everyone of us has ONE unique identity (which is different from origin or nationality). This identiy is made of and is affected by so many components (nationalities, religion, places where you lived…etc).

Now, just to show how this can be even more complicated, what would your son answer the simple question ‘where are you from?’. As you know we have a similar scenario in our family with the additional complexity that the kids hold Canadian passports. Our little ones will need to compile a very complex answer to this question .
