You said no eyelid as something different than the double eyelid, yes?
I've lived in Japan. I've seen a lot of Asian faces. But I've never heard the term "no eyelid" as a trait before.
Skin, hair, and eye color isn't where the traits end. Hair type, body type, little features in terms of nose, hands, hands, feet, jaw line, double eyelid, no eyelid, etc. There are traits that are only found in those regions that sets them apart.

But thats exactly what you're doing when you say Germans all look like this and Russians all look like that.Stereotyping is " All white people have blonde hair, blue eyes and are tall. Asians are short. Black people can run really fast. Mexicans are all short people with black hair and brown eyes. "
