I am saying that they did not come across as only victims and only a wronged party, much of which is owed to what happened to them after Red Crossing. The humans have more than enough reasons to hate the Dalish. They camp out on land that isn't theirs, their leaders are Dalish Mages, two things that Andrastianism doesn't care for. Some of their clans are also little more than thugs who prey on whomever has the misfortune of venturing near their 'territory'. Not unlike the ones you hear of from Zevran.
Before getting all the answers? Or even if you explain that the Keeper was possessed? Yes. I suppose the problem is that they were already wanting to attack in the first place and that gave them the perfect justification.
Zathrian is the leader of his clan who is willing to see his own suffer because of his hatred of humans. He's a great example of the grey morality of the Dalish. Not much unlike Loghain for the humans.
After DA II and TME, Inquisition piles on with its take on how the Dalish handled extra mages. The Dalish were already complex, adding more 'bad' on top of what little 'good' they had left was unnecessary and stunk of writer bias.
Well, I already commented on how the Dalish mage situation was not balanced. The Chantry is indirectly portrayed as being wrong about mages since the Dalish are able to have several free mages without issue. Next, if several clans were stated to be little more than thugs, what's wrong with showing those clans that are negative examples? You've just claimed that bad clans existed back in DAO so why do you take issue with such clans appearing in DAI and TME?
Well, an outsider from a race of people who have historically hated the Dalish and the former First who had to leave the clan due to use of blood magic say the Keeper was possessed. Why shouldn't the clan trust them? Them blaming Hawke and Merrill for the death of the Keeper and seeking out revenge for the presumed act is very understandable. It isn't like they would go and start massacring the people in Kirkwall afterward to repay what the clan had lost. That would have been an unreasonable portrayal of the Dalish.
Yes, I know that Zathrian is an example of gray morality, but in the first game, he's probably the worst we saw out of the Dalish whereas among the human characters we had such straightforwardly evil characters as Howe. When the worst person is a fairly sympathetic character, then the Dalish are being given a positive portrayal.
Except it really didn't. They needed the Dalish mages issue to be altered to make the mage/templar issue not so one-sided. The three mages rule made it clear that everyone has difficulty when it comes to dealing with mages and there are no easy answers.
Reasons that are never explicitly addressed during the actual scene, and necessitate understanding the lore (mainly from codex entries or having played as Mahariel) to give context as to why the Dalish are abrasive. The scene where Hawke, Varric, and Fenris encounter Clan Sabrae doesn't address how horrible the Dalish have been treated; it maligns them instead, and completely ignores how the Dalish have valid reasons to be wary about outsiders. It's similar to Sarel's negativity towards the Warden: you find out he's upset because his wife was recently killed by the werewolves, but only if your character is Dalish; otherwise, you simply think that's who he is.
That simply isn't true. You can encounter an optional scene where the clan warn templars away (who tortured one of their children), but it's incredibly easy to miss it. You can also hear about how Andrastian humans have threatened them to convert, but this is also easy to miss because it's in Act III, and requires you to go out of your way to speak to all the Dalish instead of the quest target. In contrast, the scenes that show the Dalish at their worst are always at the forefront, and even mandatory.
Clan Virnehn in TME were one-dimensional caricatures in a story where even minor human characters like Comte Pierre were allowed to have depth and nuance, and we have the 'three mage' recton in Inquisition simply to invalidate the Dalish as an alternative to the Chantry controlled Circles, adding more negativity to how most people already viewed them.
That's all well and good but the fact that such content is hard to access doesn't change that it's there and it pushes the Dalish as being undoubtedly correct in their views. You may not like the way one must access it, but it's still there and makes for an unbalanced portrayal. The Dalish are made out to be victims if you are willing to look into things, at least in DAO and DA2.
So? There are plenty of one-dimensionally cruel and selfish human characters in the series. Why can't we have a singular Dalish clan that acts that way?
Also, the Dalish were never an alternative. Their free practice of magic displays the Circles as wrong. Being an alternative would mean that it served as another option, not a group which may invalidate the actions of another.
