The reason why this discussion is still going is because Ion tried to justify his decision through ignoring the points raised. That's all there is to it. He addressed "majestic, blonde, tall and beautiful" elves as if that was the criteria these high elf fans have put forward as the sole determining elements for them wanting high leves. Even though I'm not into Alliance high elves, I can definitely see that their points have not been addressed. I can also understand why having a same-looking race on two factions doesn't sound good, but then several questions need to be raised.
What is the reason behind the continous inclusion of high elves on the Alliance side? Is Blizzard including them because they want to taunt these players? Is Blizzard including them because they want them to be important, but not playable-important? What are the exact lines at which the faction wall is shattered and which cannot be crossed? How are void elves a more sensible option when most of the arguements that are given against high elves make an even stronger case against void elves? All these questions remain to be answered and can't be dumbed down to just one thing that we all know high elves have; blonde hair and a pretty neat look.
The proper way to say no to the Alliance high elf request would in my opinion be to admit that - because of Blizzard's actions to make them like that in the first place - high elves have lead some very important plotlines for the Alliance, that they have a deep connection to the Alliance and how they would make sense to have if only blood elves didn't exist. Because blood elves do exist, it is not possible for high elves to exist on the Alliance, which is why it is a final no. This way the high elf crowd would know their request makes sense, that they're right, but that their request is not possible because of what is on the other side(without dumbing the arguement down to "majestic elves" or making fun of them despite the responsibility Blizzard bears for them requesting it in the first place). After this, Blizzard should have actively engaged in communicating with the Alliance community as to how there could be enough difference given to high elves for them to be plausible on the Alliance. Let's say a comprise through.. half elves? This is the correct way this debate should've been handled. This is why bombing them with void elves out of nowhere, on top of ignoring points raised and refusing to accept responsibility for these requests' existence in the first place, was a completely wrong approach.
