most Muslims are "white" in that they are Caucasian. When I was a child there were 3 races: Caucasoid, Mongoloid, and Negroid. Aborigine people, although very dark, were considered Caucasoid.
Then they added American/Alaskan Indian/Native as well as Pacific Islander which then included Australian aborigines, Polynesians, Melanesians, and Indonesians.
Middle Eastern people (AND DEFINITELY Syrian) people....regardless of religion...are Caucasian, and by inference..."WHITE."
Segmenting people into more and more ways doesn't bring us together.
