The "our people" phrase is a bit further than we've seen, but it's really not that far removed from the ethnic pride we see in Picard, Kirk, Chekov, Chakotay, or O'Brien.
Very good points made in your post. And you're right, several other characters refer to their ethnic roots on Earth, so it makes sense in that regard. I'd forgotten about the mask that you mentioned.
Avery Brooks is very active in African American civil rights so I'm sure he had something to do with it as well (not that that's a bad thing).
