This is the answer I should’ve written from the start.....

... and some people certainly find it offensive to be asked about what racial category they belong to. Especially when it serves no practical reason for anyone to know it.
Howcome it seems important to declare your skin color ONLY if you fit into one of the five racial categories that the US government uses to define its own population?
Yes, it is RACIAL categories that are given under the Nexus Café user profile options. They simply reflect skin color or the shape of one’s eyes. Not ethnicity which is based on common culture, and not genes. For example, the Jewish community is open to anyone regardless of skin color. Croats, serbs, bosnian muslims etc in former Yugoslavia, are all caucasians, but different ETHNICAL groups.
