This is how I see it, but I have never read anything about it.
I think it all just evolves over time, and groups decide what is acceptable. Initially, if the group has a lot of bigotry and racism against them, maybe they will reject the current label, but not necessarily.
I don’t know if it was black people or white people who pushed for the term African American, but I guess that was to switch the grouping from color of skin to national origin, but that doesn’t really work well necessarily, because there are white people from Africa here in America, and there are black people here from other parts of the world than Africa. Maybe if you go back far enough even they are from Africa originally, but they usually identify with their most recent country.
I know more than one black person who prefers black rather then African American. I ask black friends what they prefer if it comes up in a sentence that I need to use one or the other. Whatever they prefer is fine with me.
Years ago my boyfriend, whose family was from Ecuador, would answer forms that he was white. This was when the choices were often, black, white, Hispanic, Asian. I knew a black Puerto Rican woman who always answered Hispanic, and I know another PR woman who identifies more with being black. Many black people from the Islands don’t identify with black Americans as the same group. The American government I think helped change things so race is separate from national origin on forms and especially our census, so now people can choose Mexican and white, or Hispanic and Asian, etc.
America seems to have decided to call East Asians, Asians, but not other Asians. I don’t understand this at all, and I don’t know when it happened. I perceive it as happening when it became not ok to use the term Oriental. My SIL came up with being almost 50% West Asian, which is exactly what I would guess according to what we know about the family, and she was telling me her DNA results, I immediately said, “just like my sister you basically got results in line with exactly what we would guess,” but kind of over top of my response she started explaining what West Asian is, and I realized she probably didn’t know that the countries she already knows her father’s family is from are in West Asia. I blame this common use of the word Asian to mean East Asian as part of the problem, although obviously her lack of Geographical knowledge is the bigger problem. She might be an extreme example, because years ago a hurricane was headed right for Hispanola, and I asked if she had spoken to her husbands with the hurricane headed straight for him, and she told me they don’t live on Hispanola. She lived in the Dominican Republic at the time.
@jca2 Many times people ask my husband or me about how it is that he can be Jewish and Mexican.
One time in college someone asked me how I Could be Jewish and blue eyes. That’s the only time I was ever asked that, but I guess the person thought if Hitler liked blue eyes Jewish people must not have them? Just I guess, I don’t know what he was really thinking. I wish I had asked. Maybe he was thinking Middle Easterners don’t have blue eyes?
