you cannot decide what mean and what not this is not how it work
this not a notable physical difference, cause the change it not actually in the eyes, but in the glow of the eye, related to the magic they are using or being affected by, as per lore say even high elves that stay too much time in quel'thalas would have the same glowFirst, because there is at least one notable physical difference between high and blood elves: the eyes.
this is not a difference of race, a human with blue eyes is the same race of a human with brown eyes.
Again, you are using the false equivalence, dwarves and orcs are already in a distinction of genre, not just specieSecond, because orcs are orcs, and dwarves are dwarves.
Green orc and maghar orc are both orcs, both not the same specie of orcs, they have not just decades of racial difference they also came from another reality and didn't suffer the effects of corruptions by drinking demon blood
Meanwhile Warsong orcs and frostwolves orcs are both orcs YET the same specie of orcs, they just chose to rename themselves in another clan(group)
Blood elves and high elves enter in the same ground of the second, not the first one.
And alleria did have a child with Turalyon this also mean that elves and humans are the same race too?Thrall and Aggra had children. Moira and Dagran also did. No one questioned that until the high elf debate started. We even called them sub-races before the "allied race" system was introduced.
your logic is poor.
they are already countered, you just chose to ignoreThird, I'm still waiting you to counter my quotes from canon lore with canon lore that supports your position.
they are the same race
