Itâs exactly what happened though. Kaelâthas was at Dalaran, other High Elves knew he was going back to Quelâthalas, and they refused to return when their kingdom needed them.
What itâs truly biased itâs not accepting something that is canon 
Please. Put the same thing in your own words. Iâm curious to see how you view this.
High elves being cowards is just as much headcanon as them being heroic. There honestly just isnât enough focus on them to know one way or the other.
Youâre going to have to explain precisely how youâve come to the conclusion that any individual who opted not to adjoin themselves to the reclamation effort did so out of either cowardice or malice â which is the specific bias I was referring to.
âAll High Elves are cowards and harbor malicious intent for Quelâthalasâ, isnât canon. 
"In the case of the Blood Elves, yes, itâs exclusively a name.
The demonym was proposed by their then leader, Kaelâthas Sunstrider, to function as an honorific for all of their fallen kin â many/most of the Thalassians, having either lived through the Invasion of Quelâthalas or having elected to directly participate in the reclamation efforts, were more than happy to adopt the new moniker.
A minority of Thalassians rejected this new moniker, some citing general disagreements with the decisions of the government while others were simply divested from Quelâthalas completely by this point (i.e. many of those living in Dalaran, or Stormwind, or QuelâDanil)."
There isnât anything canon which even remotely implies that the High Elves behavior(s) were motivated by cowardice or malice, as a collective.
They didnât return, we donât know if it was due to cowardice, being salty over the kingdom leaving the Alliance or because they just didnât feel like it. Iâm not arguing motives, Iâm pointing out what happened.
Donât twist what I said, itâs not a good look.
Murg called them race traitors and described them as hiding, and you backed him up on that.
Blood Elves are High ElvesâŚI mean how is he âwrongâ
They are not distinct groups, quelâdorei just became the sinâdorei.
To be fair, I donât disagree with that label, never made it a secret.
However, that itâs an opinion.
What matters is that they didnât return.
Itâs absolutely your right to hide behind a clinical, textbook interpretation of your commentary, but letâs not pretend as if the implication of your words wasnât exactly as I outlined â been here for years, your modus operandi has always been the same.
Read above.
Thatâs fine. Just donât pretend it isnât bias.
Everyone has those.
Yes, but not everyone pretends their biases are canon.
The only thing Midare claimed was canon was that the high elves didnât return to Quelâthalas. This is true.
Alliance have Void Elves, Horde have Blood Elves, and both have High Elf customization
Can we please stop begging for yet another full race that looks exactly the same as two existing ones, and use that effort to develop a new race instead?
Which is ironic, since thatâs what Void Elves already are. Reskins of the original High Elves, now Blood Elves.
This
What does being here for years have to do with anything? Is it supposed to be some sort of background information on your commentary of Midareâs post?
It has quite a bit to do with everything.
Midare has years of posting history, wherein she attempts to present herself as a neutral observer â despite virtually all of her posts being peppered by biases, or contextually supportive of the biases of others.
I feel like this is just you claiming this so that the unknown passerby in the thread has doubt cast on what Midare says which is in my experience usually correct.
Also literally when has Midare claimed to be neutral on playable High Elves? Midare has always been clear on her stances lol.
