Well, unexplored doesn't necessarily mean unsettled. For example, the American settlers of the original colonies didn't explore beyond the Appalachians for quite some time, but there were still Native Americans that inhabited land far beyond the mountain range before they were even aware of the territory's geography. While I do agree that waging guerrilla warfare is hardly a good solution, you can't really argue that it isn't a solution. From our perspectives it's just a bad one.
That may be the case, but the fact that we don't know what's beyond the mountains indicates that the Dalish haven't made any attempt to find out... in 700 years. After the first 300 years, it should have been obvious that hanging around on the outskirts of civilization, and even going so far as to randomly attack humans in the case of the more violent clans, wasn't solving anything. 400 years after that, I have to wonder what's keeping them in the woodlands of nations that they hold such animosity towards. If they fear the Chantry sending Templars for their mages, that's even more of a reason to leave rather than prolong the situation by staying within the borders of nations where they are outlaws by definition. Even though I can sympathize with the Dalish, they need to come up with a better strategy if they are going to survive. Attacking humans out of "necessity" is just going to ensure that the hostility between these two groups lingers.
Ugh, this is why I hate victimization. Does there always have to be someone in the right and someone in the wrong? Shades of gray, my friends, and not that horrid fanfic-turned-novel. Keep in mind that what you might think of as necessity isn't going to be perceived as such by someone else - we all think differently. That doesn't excuse violent acts, mind you, but it explains them. Who determines who has a "right" to be a victim? In my own cultural experiences no one wants to be seen as such - let alone dependent on the goodwill of the hegemony. Which is why I find it wholly unrealistic that at least some Dalish clans haven't attempted to move beyond their dogma, but never you mind my opinion on that. It has little to do with the thread's topic.
I'm not the biggest fan of the grey morality argument. There's a such thing as right and wrong in my eyes, no matter what explanations a person comes up with to justify certain actions. I hope you'll excuse my choice of words, but once the Dalish have exhausted all possibilities and come to the conclusion that banditry is the only means of survival, then they will have "earned the right" to be considered victims. Then their actions might be considered justified rather than spiteful, hateful, and petty.
I also don't understand your dispute over the term "victim," when that is clearly the cornerstone of their argument with the humans... but you're right, this is off-topic so I'll just leave it at that I guess. I wouldn't even be talking about this had someone not tried to argue that the Dalish are only dangerous when provoked. This is simply false, regardless of what else I may think of them.
To answer OP (and this is wholly my opinion), I don't think it's a smart move politically or morally to be rid of the Chantry. It has its flaws but so does every other organization in Thedas, and for the most part it provides a conformity that is admittedly necessary for an imperialistic system. In a world that relies on balance of power, the Chantry is an important force for the Qun to wrestle with. I would also advise against stripping people of their beliefs, even if you might not agree with them. No power vacuums, pls.
Agreed, although I have my doubts about any of this mattering in the end...
