The Dalish have an astronomical amount of hubris in order to feel they are better than anyone, and this was made exceptionally clear if you saw the ending of the Solas romance.
I've never quite understood why some people assume the Dalish are a singular group of people with no divergent points of view. Elora, Cammen, Gheyna, Athras, Merrill - just a few names that prove that the Dalish aren't a hivemind with only one perspective, but an ethnic group of people with varying points of view.
I don't see why not. The Dailish claim to be trying to resurrect a society that their slave ancestors helped annihilate with the help of Tevinter. they have no idea about their own history and yet feel entitled to be completely elitist about it.
Honestly, I don't understand how anyone can be so pro any faction in this game to the point of getting genuinely mad on the forums, they're all exceptionally flawed in their own ways, and this game just happened to put a spotlight on the Dalish and their flaws. I actually laughed out loud when I heard Solas explain the face tattoos because it was just amazingly ironic and wonderful writing that the Dalish actually know nothing about their own heritage.
Actually, the Dalish are the remnants of the Dales, not Arlathan, and not every Dalish wants to resurrect the Dales; from the journal of the hunter Taniel, "The keeper says that one day the Dalish will find a home that we can call our own. But why? Why should we tie ourselves to stone constructions like the humans and the dwarves? What is wrong with the life we have now? We owe nothing to anyone, we have no master but ourselves, and we go where the halla and the gods take us. There is nothing more wonderful than sitting on an aravel as it flies through the forest, pulled by our halla. We are truly free, for the first time in our people's history. Why should we change this?"
As for why anyone would be a fan of the Dalish (or any specific group), it's similar to what Lavellan can tell Solas when he asks if he was wrong about the Dalish: they aren't perfect, but there is still good there.
I like how Sera's pub song is super popular and yet Sera finds it creepy, lol.
I must have missed that. Which pub song is that?
