Hmm...a valid point. As a real world example I'm Black. Tho..not really. I'm more a cocoa-brown color. But my "race" of humanity has at various times in history been "given" names which we wouldn't necessarily call ourselves, but have stuck because others have thought they were appropriate and after awhile of trying, some have just given up and started calling themselves that. Like the current name of choice - African American. I'm not an African American. I've never been to Africa. If anything I'm an American African, but hey, there's nothing I can do about it. Others stuck me with this race name, not me. Same might apply to Dragonborn.
