I've had a problem with "ackshun gurl" Galadriel ever since I saw the first hint that she would be swinging a sword. Galadriel never picked up a sword in any Tolkien story. Not even once.
Galadriel didn't have to because her massive power and wisdom were always implied, and briefly revealed when Frodo offered her the Ring.
‘You are wise and fearless and fair, Lady Galadriel,’ said Frodo.
‘I will give you the One Ring, if you ask for it. It is too great a matter
for me.’
Galadriel laughed with a sudden clear laugh. ‘Wise the Lady Galadriel may be,’ she said, ‘yet here she has met her match in courtesy. Gently are you revenged for my testing of your heart at our first meeting. You begin to see with a keen eye. I do not deny that my heart has greatly desired to ask what you offer. For many long years
I had pondered what I might do, should the Great Ring come into my hands, and behold! it was brought within my grasp. The evil that was devised long ago works on in many ways, whether Sauron himself stands or falls. Would not that have been a noble deed to set to the credit of his Ring, if I had taken it by force or fear from my guest?
‘And now at last it comes. You will give me the Ring freely! In place of the Dark Lord you will set up a Queen. And I shall not be dark, but beautiful and terrible as the Morning and the Night! Fair as the Sea and the Sun and the Snow upon the Mountain! Dreadful as the Storm and the Lightning! Stronger than the foundations of the earth. All shall love me and despair!’
She lifted up her hand and from the ring that she wore there issued a great light that illumined her alone and left all else dark. She stood before Frodo seeming now tall beyond measurement, and beautiful beyond enduring, terrible and worshipful.
People to whom I've brought this up have countered that Galadriel fought at Aqualonde, but there is no mention of her doing so.
But the Teleri withstood him, and cast many of the Noldor into the sea. Then swords were drawn, and a bitter fight was fought upon the ships, and about the lamplit quays and piers of the Haven, and even upon the great arch of its gate. Thrice the people of Fëanor were driven back, and many were slain upon either side; but the vanguard of the Noldor were succoured by Fingon with the foremost of the host of Fingolfin, who coming up found a battle joined and their own kin falling, and rushed in before they knew rightly the cause of the quarrel; some thought indeed that the Teleri had sought to waylay the march of the Noldor at the bidding of the Valar.
Thus at last the Teleri were overcome, and a great part of their mariners that dwelt in Alqualondë were wickedly slain. For the Noldor were become fierce and desperate, and the Teleri had less strength, and were armed for the most part but with slender bows. Then the Noldor drew away their white ships and manned their oars as best they might, and rowed them north along the coast. And Olwë called upon Ossë, but he came not, for it was not permitted by the Valar that the flight of the Noldor should be hindered by force. But Uinen wept for the mariners of the Teleri; and the sea rose in wrath against the slayers, so that many of the ships were wrecked and those in them drowned. Of the Kinslaying at Alqualondë more is told in that lament which is named Noldolantë, the Fall of the Noldor, that Maglor made ere he was lost.
There's no mention of her fighting at all. And, even if she did, what did she fight with? Magic, like the Istari? Song, like Luthien? It never says.
Her swordsmanship is only an assumption, mutated into an awful trope, and executed in the worst kind of wire-fu seen in The Hobbit films, and exists only because some people feel that women need to ape men in order to be equal. Galadriel had wisdom and latent power, like great waters behind a dam, in the stories and the first three films. It diminishes women, imho, to cast them in these silly swordsmanship roles.
