jews aren't white, unless ofcourse you consider turks and arabs to be white.
There are really only a few races:
1. White/Caucasian (Europe+Middle East+North Africa; in fact the Caucasus mountains are partly in the Middle East)
2. American Indian (originally part of the Mongoloid race; but they were isolated after the Bering Strait melted; Hispanics are mostly just Caucasian with major Amerindian influences)
3. African
4. Southern African (believe it or not, black people in southern Africa are racially more distant from western africans than Euros and people from the Middle East)
5. Australians (Papua New Guinea, Australia, etc)
6. Indians (There is a ton of debate about their racial classification)
Jews, and Arabs are usually considered Caucasian, but they are so diverse that members of a lot of races can be "Jews" or "Arabs" . Turks are completely unrelated and vary between Asian/Caucasian (as in the case of Uzbeks) to just Caucasian (like Turks from Turkey). Iranians are also, by the way, completely unrelated to Arabs and Turks.
From what I hear, racial definitions in the UK are a bit different, but I don't really know them well.
Lol. I spent way too much time on this post.
