We are so-called Caucasians. We were living in Alaska when our son was born. He amused himself on taking the PSAT test, by checking off the box for "Native Alaskan." His classmate, a so-called Caucasian who was born in South Africa to a white South African family who later immigrated to the USA, wondered if he should check off the box "African-American."
By the way, what "color" are people who actually live in the Caucasus, how do they describe themselves, and how did we "white folks" happen to be called Caucasians? My ancestors came from Ireland. I think there is a new book out called "The History of White People" that tackles this bizarre subject.
