I can tell that you get it. So, I don't mean for this post to be a refutation of what you've said.

I just want to point out, for those playing at home, that one (race) is biological and the other (ethnic groups) is more cultural or social.

So, for example, in today's vernacular, the vast majority of people who are Jewish, Irish, French, German, Spanish, Italian, Greek, Polish, Danish, Norwegian, Finnish, Austrian, Belgian, Scottish, Welsh, Russian, Ukranian, Swiss, Croatian, Czech, Hungarian, Slovakian, Bosnian, Latvian, Serbian, Bulgarian, Cypriate, Belarusian, Lithuanian, Romanian, Montenegran and Albanian, could all come to the United States, and, if asked to specify their race, could get away with simply saying .......

....."white."

Yet, they are not one collective 'ethnic group.'

So, I understand how dictionaries can sometimes be linguistic sculptors, shaving the barbarous edges off of offensive concepts to make them digestible in an academic environment.

Still, some words lose something in translation to how they are meant and used in every day life.

Kind of makes one have to consider re-thinking the whole Rachael Dolezal thing. Doesn't it?
