This sounds like ignoring the fact that there are common feature sets associated with various ethnicities. Mentioning uncommon traits among those groups seems irrelevant since it wouldn't be associated with the ethnic traits of the group. I'm sure just about every eye color or hair color has appeared in just about any ethnic group, but when they are uncommon like the ones you mentioned, the uncommon traits won't throw away every understanding and association of the ethnic groups with their common physical features. That wouldn't make sense.
Those aren't mutually exclusive as your wording implies. Quite the opposite. You can tell the difference between an Asian person, black person, Middle Eastern person, white person, etc., based on common physical features. Race and ethnicity do have associations with physical features and appearance. We as people can recognize the distinctions based on the common features of the ethnic group, and that part is okay.
I'm feeling like people aren't maybe sure what racist means. It isn't simply everything that is associated with race, that's for sure.
I never forget these boots.
Well, I would say that's not always the case. In any case I dare say race and ethnicity are social constructs.
