I wonder who chooses not to disclose? Roswellians? Lizards? Alpha Centaurians?

Those protesting the system, me thinks.

I just pondered the list and wondered where for example South Africans of Indian descent fits in. The list is such a mix of geography, skin color, culture and language. If they had a cathegory based on religion (for example jewish or muslem) I think they would have covered all the big bases of dividing people into 'races'.
