The word was assigned to humanity by the Arlathan elves. As you claim to know the original word, what was it?
What are you talking about?
I never claimed the elves had an original word for Humans. I said the opposite. The elves didn't have an innate word for humans. They assigned pre-existing words which they use as a pejorative.
And once again, why would the Dalish change anything? Have they cause? Have the humans dropped their racism? Hate breeds hate, but don't ask the underdog to drop theirs first. The olive branch needs to come from those with the upper hand. As it stands, xenophoby is the only rational stance the elves can take.
In order-
I don't expect them to.
Yes.
Human racism is irrelevant to Dalish addressing Dalish xenophobia.
'Underdogs' have no special exceptions to being judged on the basis of xenophobic attitudes.
It doesn't, even if we ignore that the humans don't even see themselves as being in a race conflict and thus have no olive branch to give.
It really, really, isn't, unless rationality means ignoring how well it has worked out for them.
As for their culture, the Dalish know their culture very well and its origin in the kingdom of the Dales. But i suspect you are referring to Arlathan. Arlathan culture has nothing to do with the Dalish other than serving as a mythical, idealized banner to rally around. The actual culture was eradicated allmost completely long before the Dales came to be and the elven culture that followed was a new one built on fragments. All they really share with original Arlathan are the gods. Every culture has a mythical 'golden age' which they ever strive to restore. It gives people purpose. And in every case the truth tends to be less golden. That doesn't suddenly invalidate the culture.
The Dalish believe their culture is Arlathan in nature. It's not merely an idealized past- it is the diminished present, with each relic and ritual they practice restoring it, and it is the desired future (which is little more than a hazy blur of that the Humans will somehow disappear and leave the elves to reclaim everything).
The fact that contemporary Dalish culture has almost nothing to do with Arlathan is a verdict of the outsider perspective which doesn't dip into the coolaid or whatever it is the Dalish drink. The Dalish cultural narrative is that Arlathan culture is reclaimable, with the Dalish being the guardians and maintainers of 'true' elven culture. City elves have 'forgotten,' contrasted to the Dalish who remember, recover, restore, and revere the old ways.
The invalidation comes from the reality that you describe- that the Dalish project of elven cultural restoration is fatally flawed because the Arlathan context (cultural, political, identity) is irrevocably lost and the Dalish practices which they claim as the True (Original) Elven Culture are really nothing more than often mis-informed reenactments.
