Totally! I first started thinking about this when I was talking some Roman History with my mom. I mentioned people like the Gauls or the Germanic tribes, etc. and my mom would ask me, “What race were they, though?”I fumbled the answer; they were White, I guess? To which she asked, "but were they French, or German?" Which really cuts to the heart of how deep ethnic nationalism has permeated the way we think about other people. The ancient world mostly used language - not appearance - as their cultural identifier. If your first language was Greek, you were Greek. Since mobility and mixture of various groups occurs all the time, the classical liberal definitions of race really shore up as inadequate and irrelevant! Hopefully, just as with gender, we can start allowing self-determination become the primary method of identifying race in the future.
