No, I'm sure it's all perfectly logical and there's a lot of science to back it up, but I'm a layman, not an anthropologist. Race doesn't mean that to me, nor is there any reason for me to think in those terms. In terms of Dragon Age, "race" specifically refers to elves, humans, dwarves, and qunari. There is no separation between Dalish and City Elf, since they are physically the same type of creature and are separated only by culture (which is even further divided by region). My original point was that there is obviously a racial (or ethnic if you prefer) difference between a poor human and a city elf, but no such difference exists between Dalish and city elves...
There was also a comparison between the TES Mer... I'm just going to call them races, you know what I mean... races, and DA elves, but in that case there is an obvious divergence between the three types that does not exist between Dalish and City Elves... there's really nothing at all that's different about the two groups of DA elves besides culture, so the claim that one is "less elven" than the other doesn't have much of a foundation...
I'm not asking you to change how you use your language - that wasn't my intention, although I can understand why it may have come across that way. For my own purposes it works quite well, but if how you utilize the word works in your own life, then of course you should feel free to continue using it as you see fit.
As for that argument, I use "species" because humans and elves are very clearly not of the same ancestral descent. If you could prove that at some point down the evolutionary chain elves and humans were once one, I might begin using a different term. As far as I am aware, in the lore, it seems that humans evolved separately from elves, just as qunari did. Before you can even begin to apply race to something you have to apply ethnicity, and before ethnicity you have to apply species. That's why I use the definitions I do, but I understand that not everyone does. Ethnically I claim that the city and Dalish elves are the same, as they all have common ancestral roots in the Dales and the Elvhenan slaves beforehand - there's no arguing that - and they have not had the time to grow ethnically diverse in the way humans have. Humans can be Rivaini, Ferelden, Antivan...those all have very distinct appearances, although a claim that they are ethnically different would of course have to be made through genetics, which I doubt BioWare would ever provide. Racially though you can certainly argue they are different - an Antivan might look at an Orlesian and say "human" if the label was accurate, but they would not say "Antivan," because they do not consider someone who does not share that culture (or perhaps even a distinctive appearance) to be Antivan. So applying this to city elves and the Dalish, they might be racially different on the basis of something as simple as culture. I might define them this way, but I don't think you're wrong for disagreeing - I use race to distinguish between the two because of the growing divide between their shared cultures, and because ethnicity does not seem the best label.
Like I said when I brought them up, the Dunmer and the Altmer actually share genetic ancestors in the Aldmer. Dunmer were once called Chimer, but left Summerset Isle for present-day Morrowind due to irreconcilable differences in culture (chief among them being religion). Appearance-wise (and perhaps genetically-wise as well), Chimer did not change until the Battle of Red Mountain in 1E 700, after which they became the Dunmer due to Azura's curse. Over time, races may become ethnically distinct, but this was not the case for Dunmer (at least not at this point). And as we cannot prove genetic changes without the developers, simply guess at them, racially distinct is more accurate than ethnically distinct. I'd like to expound upon the Bosmer, but sadly, I know very little about their origins. :/
And course, the city elves are no less elven than the Dalish! If the city elves were less elven they wouldn't be called elves, now would they?
