I think it’s also important to note, though, that what’s underlying Wynne’s sentiments here is fear.
She doesn’t say ‘I think the brightest future we can have is by working peaceably with the chantry’. She says ‘our only hope for survival is to show them we can be trusted’. And this comes from a lifetime of internalizing that people are justified in fearing mages (because of course, that’s what Circle mages - and even those outside the Circle - are always told), and believing that it’s this fear that needs to be defeated. If only they weren’t afraid of us, many mages think, then everything would get better. If only Bad Mages would stop giving people reasons to hate us, then we could show them that we’re not all like that; we could earn our freedom and livelihoods by defeating fear.
Except, the fear of mages (not magic - mages) in Southern Thedas is something the chantry encourages. It’s basically hard-coded into their take on Andrastrianism, and is one of the cornerstones of their politics. Fear of mages is what helps rally people against Tevinter, and it’s what ensures parents turn their mage children over to the Circle, and supply the chantry with free labourers and the nobility with exclusive access to the best healers and long-range combatants in the world. It’s what provides the chantry with any templar recruits who aren’t conscripted from the orphanages. There is no recourse for assuaging that ‘fear’, because the people who keep perpetuating it are engaged in a calculated form of propaganda, and have no interest in ending it. They benefit from it. They actively encourage it, so it’s not a genuine misunderstanding by any stretch of the imagination.
Wynne’s approach is exactly what the chantry wants. Mages working quietly to try and gain more autonomy, which they will never be granted because the condition of that autonomy is ‘well you can have it when you prove you can be trusted with it’. And then, invariably, some mage does something bad (because even if mages never had a reason to be desperate or take drastic actions, you’re always going to have asshole mages - there are assholes in every group in the world), and this becomes the excuse to tighten the leash and put off all those pesky issues of freedom and individual rights. This whole conversation demonstrates the problem, really - Wynne brings up Kinloch Hold as an example of why the Chantry might currently hesitate to let mages govern themselves. What she doesn’t seem to realize is that there is always going to be something. Some Circle with troubles, some rebellious mages with issues, some maleficarum stirring up nonsense, or hell, even just Tevinter continuing to exist, will provide the Chantry with the means to go ‘mmm, I dunno, you guys don’t seem like perfect saints to me yet - best we keep on imprisoning you, executing you, and cutting out parts of your essential beings to turn you into obedient labourers whenever we feel like it. But, oh, of course, just as soon as you achieve a level of monolithic virtue that literally no group of people has ever achieved before, you’ll be free to go. I’m sure it’ll happen for you any day now.’
It’s hard to blame Wynne for wanting to believe it could work out, though. Just like it’s hard to blame Vivienne for hating the war. Violent conflict is… well, violent. And it’s very hard to instigate a revolution when you know that, by the same stroke, you’re definitely consigning vulnerable and innocent people to die in the fallout. The Tranquil, the little apprentices, the elderly, ill, or disabled mages, the ones who aren’t good at fighting or casting big spells or surviving exposure to the elements - these are the people who will be cut down, who will suffer once the situation turns to full-blown rebellion.
I think it’s really telling that Wynne and Vivienne are both people who express a lot of distress at the suffering of, like, mage children, or Tranquil. Viv gets very upset over the Tranquil skulls issue in DA:I, and when we meet Wynne, she’s doing her level best to protect the apprentices from the abominations roaming the halls. Circles are communities. The same mages who have to decide whether or not to go to war are the ones who teach the young apprentices, who grew up with Senior Enchanter Marvin who’s faulty hip means he’d never be able to run in a crisis, who knew Tranquil Gwen back when she was an eight-year-old girl who cried from homesickness and missed her mother’s hugs.
The templars have much less dilemma. For example, someone like Cullen would never have to worry that going to war with the mages would mean bringing along his sister’s children, and watching them struggle or go hungry or be cut down by enemy swords. It makes it hard for me to be at all angry with Wynne, or any other mage like her - they want to find a peaceful resolution.
It’s just, they can’t, because the chantry is not a peaceful organization. And that’s heartbreaking. It’s sincerely awful that there’s really no recourse for the people who genuinely don’t want to hurt anyone, to obtain the basic rights they need to avoid being killed or violated on a regular basis.
