"Just as she, and now I after 50+ years of close proximity to Asians see subdivision within the group called Asian; Chinese, Japanese, Koreans, Southeast Asians, Indians have subset physical characteristics within the larger group."

I don't want to argue either, but I can't resist asking, do you see these groups (Chinese, Japanese, Indian, etc) as distinct races? How about the Mongolians and the Nepalese and Thai? Or the Kazakh people, who it's difficult to describe as having typically Asian or European features. Is the race Asian? With these smaller subdivisions within that race? Or are they all different races?

You keep saying race exists, but I'm still not clear what you mean when you use the word. For example, you talk about people being unable to distinguish between different groups, this is obviously something that happens. But this is simply a failure of pattern recognition due to a lack of exposure, no? It's not evidence of racial categories, it's evidence that some people don't make nuanced observations if they're not used to seeing people who don't look like them.
