So they weren't a part of the kingdom of Quel'Thalas that you yourself mentioned? Fascinating. Because what you "forgot" to mention is that Blood Elves aren't just the dominant faction, they are the ones in control of it, with direct continuation of power from Anasterian to the current regime. Alleria not being around when Kael made the purely symbolic decision to commemorate the fallen by slapping the Blood Elves name on them doesn't change that. Nor does it mean she doesn't owe her allegiance to the current leadership, because that's not how nations work.
Meanwhile Freehold is literally described as free people's fort in the story and isn't a part of the Alliance. So it's kinda obvious you wouldn't be a traitor to the Alliance for killing a bunch of unaligned pirates and mercenaries. This example tries to distort the topic to that of race. It's not. If High Elves killed only a bunch of Felblood, San'layn or Wretched they'd be free of the blemish of treason, even though are all Thalassians.
Yes, saying someone's argument is so short-sighted that it hurts is totally not throwing shade at them. Very convincing. And sorry to burst your bubble, but I don't need to declare that I am right, when the lore is right there for everyone to see. And since you're already moving the goalposts (by around 20 parsecs no less) just one paragraph below, if anyone's declaring victory for me, that'd be you by doing so.
And please spare me your trite BS about how my only argumentative skill is "mindlessly shouting my own right" (speaking of which, I'm sure "in your opinion" that's also totally not you throwing shade at me
), when unlike the Alliance team of fanfiction peddlers I can actually source my arguments. Which, you know, I've done in the very post you're quoting here and trying to misrepresent. Though I suppose if you start from the position of rejecting canon and substituting it with made up nonsense the act may appear "mindless". Also, if we're already delving into argumentative skills of different people, the only argumentative trick you lot have got is playing the victim when your headcanon is called out for what it is and pretending it somehow magically vindicates you. Here's a free piece of trivia for you: it doesn't.
What I "imagine" is that just one post ago you tried to pretend Alleria had no way of even knowing that Quel'Thalas even left the Alliance in the first place and assumed it would at most be neutral. Now you're trying to harp on her sources being biased in order to salvage your lie. Which is not very effective. For multiple reasons, even. Starting with how whether her sources were biased or not doesn't change the fact she did have sources, which already exposes your blatant lie for what it is. Secondly, while Vereesa is rather zealous when it comes to the Blood Elf topic, Arator has never expressed any such behavior.
Thirdly, as it is indicated by my second example that you dishonestly cherry-picked out, Vereesa and Arator weren't her only sources anyway. So even if Arator is as biased as Vereesa, that doesn't change anything. Because her final source is Anduin, who sent her to Silvermoon to convince Lor'themar to rejoin the Alliance. And whatever bias Vereesa and Arator may or may not have used to sway Alleria, Anduin is so pure he gets bone aches from his holy bones when he as much as thinks a bad thought. So it's rather implausible he'd have tried to deceive Alleria with false portrayal of the situation.
Finally, how does bias even enter the picture here? Whether Quel'Thalas left the Alliance or not is a matter of fact. It either left it or it didn't and is still a member. So while Vereesa may have painted the
circumstances pertaining to the kingdom leaving the Alliance in a negative light, the same does not apply to the factual issue of Quel'Thalas' allegiance to the Alliance itself.
Weird, I thought I had to wear you down so that you wouldn't even bother and then I'd declare victory. Yet here you are admitting she's indeed a traitor. Fascinating.
Also, Alleria lost her genocidal hatred even before the end of Beyond the Dark Portal thanks to Turalyon and between then and now she also spend five hundred years fighting the Legion and another five hundred in a Naaru prison, so I'm not sure how said hatred still matters at this point.
When did the Thalassian leadership make such assumption? And Lor'themar did not "consider her a ranger of Quel'Thalas" in the slightest. What he actually called her is a "guest" and "a hero of Quel'Thalas' past". Even if there was no deeper meaning behind the "past" part, there's no mention of her still being a ranger there. He also openly expressed mistrust of her on the grounds of her Void connections.
Also, yes, desertion is still desertion regardless of what other people assume about you. Such assumptions are totally inconsequential, the only thing that matters to determine whether one has deserted or not are their actions. Also, no one said anything about desertion being permanent, deserters can return, which does in no way unmake their desertion. But desert she did, in more than one way. Her going AWOL on a personal Orc hunt was already an act of desertion in and of itself. But joining another military without authorization, which she did when she joined the expedition to Draenor, can also be considered desertion depending on the jurisdiction (it is the case in US, for example).
And that wouldn't be correct either. First of all, the High Elves that are affiliated with the Alliance right now didn't "remain" with the Alliance. Quel'Thalas left the Alliance shortly after the Second War, meaning that they had to team up with the Alliance again. Secondly, applying this label at all High Elves is misguided. Because the current meaning of a High Elf stems first and foremost from the simple fact that Kael didn't gather all survivors of the Scourge's invasion. He only gathered 90% of them because the rest were, for one reason or another, out of his reach. And he renamed those survivors the Blood Elves, unaware of the rest. And while many of the other 10% did join the Alliance, some did not. So they're not all traitors.
