I support a very specific kind of rebellion,
Yeah, that is what I said.
I would put every death that occurred during the Annulment on Meredith's (insane, tyrannical, blood-soaked) shoulders, for starters. However, Elthina was her enabler, the snake in the grass who encouraged her to topple Kirkwall's legitimate government in the name of the Chantry and Orlais. Elthina and her priestly cronies shares Meredith's guilt, not even mentioning her other crimes. Elthina encourages Petrice's zeal, extorts money
from the lowest in Kirkwall, and does nothing as Meredith's misrule destroys Kirkwall from the inside out.
Without such a leech draining the city, it will be able to move on and recover from what it inflicted. She had to go, and the scale of it was good for making the Chantry understand the fear it inflicts every day, and not just on mages.
Lore is kind of an optional thing to you, isn't it?
I mean, what does it matter if everything from the game to World of Thedas Volume 2 will point out how Elthina was one of the most beloved Grand Clerics in Thedas with entirely benign motives when you have to justify mage supremacism by pretending it's for everyone's good?

What does this even mean?
First of all, Elthina and the Chantry weren't draining Kirkwall of anything unless we consider every Chantry on Thedas to be doing the same. In fact, we routinely see Sisters talking about aiding the poor and we see them asking alms for them.
Second, even if what you claimed was true, nothing would be changed because, guess what, the people of Kirkwall didn't come to a realization that Elthina was a leech and removed her. The Chantry will just be rebuilt and there will be another Grand Cleric.
