"What people want to be called" reminds me of an experience early in my career in Federal personnel administration. We (the VA) wanted to get all of the possible points for employing "minorities", especially in professional and supervisory positions, so we were sent a printout of the "racial" breakdowns among our employees, which was based entirely upon their personal self-identifications. It said that we had no Negro (the term then in use) physicians, which seemed to me to be incorrect. I went to speak to the member of our staff who was from Ethiopia (and who was very dark-complected), and asked him for permission to "correct" his records. He told me in no uncertain terms that (1) Negro only referred to people from south of the Niger River, (2) that he was a direct descendant of the Queen of Sheba and (3) he considered himself to be a Caucasian (the term then in use). I said, "thank you, doctor", went away, and his record remained untouched.
