December, another source for calling Asians Asians rather than Orientals can be found in “Everything You Need to Know About Asian American History” by Lan Cao and Himilee Novas. I’d type it all it, but I’m too lazy and don’t want to violate any copyrights. Page xiii. Asian describes a person- Oriental describes a rug.
My son is Asian. He is too young to have preferences (other than what to wear - don’t let a toddler dress himself!), but I get to have preferences for him - Asian please. I forgive Oriental from people who don’t know better (my 85 year old grandmother). Actually, I forgive it from anyone as long as it wasn’t used with malice – I wouldn’t forgive someone for using Asian with malice either.
Technically, he is Korean. And for people who know that Korean is the preferred term. But other Koreans occationally think he is Chinese - and there is very much a racial hiererachy amongst Asians - you will probably offend a Japanese person if you mistake him for Chinese or Korean - so you are better off just with Asian unless you know. Since you know the nationality of your coworkers, refer to them as that (and lumping them together probably is rude - why would you ever refer to “all the white folk that I work with”).
Also, Oriental often refers (probably in the case of the Oriental Institute) to persons from the East (or things to do with the East like history or art). India and the Middle East are lumped together with Asians (China, Japan, Korea, Thailand, etc). Oriental, in that case, would be the best possible term.
If you don’t have a reason to refer to people as Asian or Asian-Americans you don’t have a reason to use the term Oriental either. I agree, if you can get around using any term, its better not to describe someone by race - especially a group of someones.
