You misspelled "Clan."
Unless you truly, seriously believe there are only 3-4 Dalish Clans in all of Thedas, the 2-3 we've seen so far are NOT a "numeral majority" in any sense of the word. Even if there were only 10 Dalish Clans in all of Thedas (which I seriously doubt), the 2-3 we've seen are not a numeral majority. You are using a numeral minority to judge the majority or entirety of a group, based on a sample that is too small to represent everyone.
It's a fallacy. Your logic is both prejudiced and fallacious.
And as long as Andrastian humans believe that Andrastianism is the One True Religion ("There is One Light, One Word, One God"), that anyone that doesn't believe in the Maker and The Chant of Light are evil heathens and savages, that the Maker left the world because of humanity's own sin in trespassing on His Golden City and betraying/killing His bride, and that the Maker will only return when the Chant of Light is "sung on all four corners of the earth," then there will never be true peaceful or civil interactions between them and the elves. If humans' good will toward others depends on others being Andrastians like them, then they will never truly tolerate or accept people trying to practice their own culture and religion. The elves have their own culture and religion that they want to practice without humans breathing down their necks, telling them they need to give up to be like them.
What? Not ALL humans are bigoted, intolerant, proselytizing fanatics that believe everyone has to follow the Chant to the letter like them? Not ALL humans spit hate at every Chasind, Dalish, or Orzammar dwarf they see because they don't follow the Chant of Light like them? Some or many Andrastian humans are just as friendly, engaging, and obliging toward non-Andrastians and non-humans even though the Andrastian religion's fundamental belief is "Human Andrastian > non-Andrastian"?
Then why on earth do humans' fundamentally "intolerant" culture ("You have to be like us OR make room when we force our way through because our Chant of Light being sung 'on all four corners of the earth' comes before your right to keep your own traditions and beliefs") not automatically make them all intolerant jerkasses, but the Dalish's basic belief that they want to regain their culture, religion and possible immortality without constantly being in the company of humans (who history has shown will not respect their privacy, religion, or way of life) automatically makes them all intolerant jerkasses that deserve what they get?
Klan and Clan are both proper spellings of the word with the same meaning, it isn't a "misspelling" i could also call them wandering vagabonds if you like.
It is the numeric majority in what has been presented thus far, Your blatant misuse of my own words to belay that very notion doesn't make it so, its compounded evidence, not fallacy.
And in response to the Chantry teachings of Andraste being strictly human i'd point out that given Humanity is the majority species of Thedas that is merely the reflection of a wide spread faith being adopted by that majority, it also has within it Dwarves and Elves. And it being incomprehensible with foreign cultures i'd point out that it has trading relations with folks who venerate their own Ancestors, And it isn't invading Par Vollen to be rid of Oxmen who believe in no deity at all, little lone the Maker. You have varying contradictions of course but that's all faiths, all beliefs i don't deny that.
But i don't paint The Dalish belief beyond what it is, Isolationism done in the name of their culture, its just that simple, I don't label them war starting, blight ignoring murdering bigots do i? Well occasionally i do but that isn't the point. I also point out that according to them, Humanity is the cause for elves losing both culture and immortality, along supposedly with Magic which also faded from the "quickening" so how exactly does Peaceful Coexistance occur with that belief in circulation? You Dalish defending lot seem to overlook their culture it self prevents it as much as the "Chantry's intolerance of gods being put before the maker"
Also given the Dales invaded Orlais wouldn't it be the opposite what them deliberately biding their time and waiting through a blight before marching on them? Or was that somehow a "Orlaisian" Breach of "Privacy"? By not wanting to be invaded and striking back. Furthermore their culture is predispositioned and preconditioned to maintain this stance, even if it is proven wrong, They will maintain they were wronged, robbed and other victimizing nonsense just because that's how you sustain an isolationist culture, you make yourselves out to be the victim when you in most cases are responsible for your own suffering.
Ultimately it comes down to this, Bioware has portrayed them in this fashion for two games now, that is been the face we have been presented with and its a face that some such as myself have just come to accept, because their culture cannot give anything else. There are a few exceptions within individuals but those are exceptions and not norms, So ultimately you were right on one point.
They do deserve what they get.
