The door of durin.

About the feud: The dwarves of Moria may have not been involved, or have been dwarves of Belegost. It was mainly the dwarves of Nogrod that were involved with the Silmaril incident.

Actually, the feud started when Aule, one of the Valar, made the Dwarves without telling Iluvatar. Iluvatar says,"...and often strife shall arise between thine and mine, the children of my adoption and the children of my choice." His children are the Elves and Men. He never intended to make Dwarves. That is why they are the children of his adoption. Anyway, I think that is the main reason for the feud.

Since everyone else calls it Moria, why would the Dwarves resist. Perhaps they still call it Khazad-dûm when they talk amongst themselves...

Well, I've always seen dwarves as stubborn minded, though that feeling may've came from another book that I was reading. So, if dwarves are stubborn, then logically, they would keep to calling Moria: Khazad-dûm. Though one must think, because everyone else always called it Moria, as it was by the dwarves in the Hobbit, then the dwarves, out of politeness, would've called it Moria.

I suppose that it would depend on the company that the dwarves were in. With some people, they would've used Khazad-dûm, while with others: Moria.

It would've depended on the dwarf.

But one wonders, if it was the Dwarven door, how come Celebrinbor didn't use Runes, instead of Tengwar... after all, it was a stone door, and have you ever tried to carve Tengwar into anything? It's not easy. However, the Runes are all straight lines. How come they didn't use Runes on the gate?

Sorry, just a random question that I hope adds to the topic, after all, it does indeed have to do with the Doors of Durin. (Pedo mellon a mino...)

In answer to your question, Eowyn Skywalker: Because Celebrimbor was an elf, and so he would use elvish no matter how close a friend he was to any dwarf. And most likely no elf and dwarf were close at all until Legolas and Gimli. And elves were the only ones who knew the skill of writing the script in the 'moon-letters', I believe. Another answer to that question can be found in Voralphion's post:

The doors were written in elvish because the western door was the one mostly used by the elves of Hollin when the dwarves and elves were friendly.

It could be that Moria was simply a mistake made by Tolkien. It must have been nearly impossible to keep up with an entire mythological history, including as small of details as the changing of names over time. But it could also have many other purposes. For one, Moria could always have been Moria, though the darkness of its name would simply be descriptive, and would not have to signify fear of it. Perhaps it was inscribed so to foreshadow later events, and because of these later events was adopted as the common name for it.

What's so derogatory about "Moria" from a Dwarf's perspective anyway? A Black Pit is the best place to go mining, after all.

I think Eowyn Skywalker is right.

Though one must think, because everyone else always called it Moria, as it was by the dwarves in the Hobbit, then the dwarves, out of politeness, would've called it Moria.

I suppose that it would depend on the company that the dwarves were in. With some people, they would've used Khazad-dûm, while with others: Moria.

e.g. Gloin when speaking at the Council of Elrond uses the word Moria:

Some spoke of Moria: the mighty works of our fathers that are called in our own tongue Khazad-dûm

Moreover, on Balin's tomb "was written in the tongues of Men and Dwarves: Balin, Son of Fundin, Lord of Moria" as Gandalf said.
When you read the runes, the lower (smaller) runes mean just that, in English (= the common tongue) while the upper part reads "Balin Fundinul Uzbad Khazad-dumu"
So while speaking in the common tongue, the Dwarves used Moria, and it certainly wasn't any intended insult ore practical joke on Celebrimbor's part!

But one wonders, if it was the Dwarven door, how come Celebrinbor didn't use Runes, instead of Tengwar... after all, it was a stone door, and have you ever tried to carve Tengwar into anything? It's not easy. However, the Runes are all straight lines. How come they didn't use Runes on the gate?

I think they were not exactly carved, but kind of painted with "Ithildin" which contained Mithril.
