It need not be viewed as positive or negative if one sticks to their racial/ethnic or other background or not. Probably in the future all people will be a mixed golden-brown color, great, but no value judgement is in order. And like Samuel says, Jews are a people, not a race, though most Jews (European Jews too) are Semitic, as are most Arabs. In Israel you see all shades from very light-skinned Arabs to very dark-skinned Jews and vice versa. But since most of both peoples are Semitic, and since we also have very close languages, the screams of "racism" on either side of Arab/Jewish conflict are but vicious ignorant lies. Dark-skinned to light-skinned, Jews and Arabs pass as each other always, every day. That's something the Israel-haters just love to ignore, deny or forget. For whatever it's worth, interracial mixing does seem far more common in Israel than in most other nations. And Arabs and Jews also mix far more freely and casually here than the Maureen Anns would ever believe.
