Ahem

I'm in favor of a list of nationalities like...
- Slavs
- Scandinavians
- Europeans
- Latinos
- Peoples of the Caucasus
- Arabs
- Indians
- Mongoloids of Central Asia
- Mongoloids of South Asia (China and other related groups)
- Mongoloids of the Far North
- Mongoloids of the Far East (meaning Japanese, Koreans, Vietnamese; to me, they all look the same, so an expert is needed)
- Native Americans
- Black people (again, there are different types of black people, and it's easier to distinguish them, but I don't remember the names)
- Polynesians (Papuans like Maori and Australians, etc.)

It might not be entirely accurate, but this list personally resonates with me more than Alex's list because I can't tell an Englishman from a Frenchman without a drink, but I can recall general types of peoples.
