I meant race. We’re only talking about skin color here.
“Today, race refers to a group sharing some outward physical characteristics and some commonalities of culture and history. Ethnicity refers to markers acquired from the group with which one shares cultural, traditional, and familial bonds.”
Race does exist (as does racism, unfortunately), and Wikipedia does have a page on race, as does any dictionary you choose. It would be a fair point that people should be sensitive to which word they choose based on context, and race is sometimes not the right word, but in this case it is the better choice, and the distinction in this context between race and ethnicity isn’t super relevant.
People of different ethnicities can differ by something as minor as just language and language-related culture, such as for example Czechs vs. Germans. So surely ethnicity is not the applicable term here.
