Nope, and this proves Aucald's point even further. What you are debating are "playable races" . Just because say Taunka are not playable doesn't mean they aren't a race in so far as WoW is concerned.
And what Blizzard considers a "playable race" is completely arbitrary because they do not all follow the same rules. I can make a White Draenei right now who would be similar to a Lightforged Draenei sans yellow eye color, yet it's the yellow eye color that is separating the LF Draenei from the regular Draenei. But this isn't followed with Blood Elves for example - who received Golden Eyes are still members of its same playable race.
You can make a Dark skin/Red eye Dwarf to makeshift your "Dwarf race" as a Dark Iron, but Dark Iron are still truly a separate category. Now that Classic is out the resemblance is even more crazy, your dwarf character in Classic can very easily look like a Dark Iron Dwarf.
Blizzard have gone on record for stating that Kul Tirans are Humans therefore they don't even consider Kul'Tirans a separate race but put them into a separate "playable race" category.
And this has been the whole point of Aucald's recent posts, if we aren't settling on the terms we're discussing it's just going to be a bunch of talking past one another thinking "I have the correct definition".
Besides, other than CM Ornyx, there hasn't been an actual clarification of what races mean other than his post:https://us.battle.net/forums/en/wow/...9267207#post-6
Where he pretty much states, "it's more that when you play a Human or a Blood Elf, or any other race for that matter, your character comes from a specific "faction" within that race."
"Playable Humans are always from the nation of Stormwind. Playable Blood Elves are always from Silvermoon."
This is also why you will never get the High Elf experience players are asking for just by "making a Blood Elf". Because the Blood Elf starting experience is not the story High Elven members of the Alliance went through at all.
