Yeah, right. She "only" was the first person to notice that Frodo would never recover from his wounds, and she "only" gave Frodo "her" place to the ship to Valinor. But you see, that's DOING NOTHING because she doesn't fight in a battle. Whatever. If these people are too short-minded to see it, if they don't understand the real theme of LOTR, that's not my problem, neither is Arwen's, but please, for the love of Iluvatar: stop saying bullshit.
You don't belive me? Read this extract from the letter #242 (The Letters of Tolkien) in which Tolkien talks about Frodo after the war of the ring; he also mentions Arwen there.
He appears at first to have had no sense of guilt (III 224-5);1 he was restored to sanity and peace. But then he thought that he had given his life in sacrifice - he expected to die very soon. But he did not, and one can observe the disquiet growing in him. Arwen was the first to observe the signs, and gave him her jewel for comfort, and thought of a way of healing him.* Slowly he fades ‘out of the picture’, saying and doing less and less. I think it is clear on reflection to an attentive reader that when his dark times came upon him and he was conscious of being ‘wounded
*It is not made explicit how she could arrange this. She could not of course just transfer her ticket on the boat like that! For any except those of Elvish race ‘sailing West’ was not permitted, and any exception required ‘authority’, and she was not in direct communication with the Valar, especially not since her choice to become ‘mortal’. What is meant is that it was Arwen who first thought of sending Frodo into the West, and put in a plea for him to Gandalf (direct or through Galadriel, or both), and she used her own renunciation of the right to go West as an argument. Her renunciation and suffering were related to and enmeshed with Frodo’s: both were parts of a plan for the regeneration of the state of Men. Her prayer might therefore be specially effective, and her Plan have a Certain equity of exchange. No doubt it was Gandalf who was the authority that accepted her plea. The Appendices show clearly that he was an emissary of the valar, and virtually their plenipotentiary in accomplishing the plan against Sauron. He was also in special accord with Cirdan the Ship-master, who had surrendered to him his ring and so placed himself under Gandalf’s command. Since Gandalf himself went on the Ship there would be so to speak no trouble either at embarking or at the landing.
It is clear, of course, that the plan had actually been made and concerted (by Arwen, Gandalf and others) before Arwen spoke. But Frodo did not immediately take it in; the implications would slowly be understood on reflection. Such a journey would at first seem something not necessarily to be feared, even as something to look forward to - so long as undated and postponable. His real desire was hobbitlike (and humanlike) just ‘to be himself’ again and get back to the old familiar life that had been interrupted. Already on the journey back from Rivendell he suddenly saw that was not for him possible. Hence his cry ‘Where shall I find rest?’ He knew the answer, and Gandalf did not reply. As for Bilbo, it is probable that Frodo did not at first understand what Arwen meant by ‘he will not again make any long journey save one’At any rate he did not associate it with his own case. When Arwen spoke (in TA 3019) he was still young, not yet 51, and Bilbo 78 years older. But at Rivendell he came to understand things more clearly. The conversations he had there are not reported, but enough is revealed in Elrond’s farewell III 267.3 From the onset of the first sickness (Oct. 5, 3019) Frodo must have been thinking about ‘sailing’, though still resisting a final decision - to go with Bilbo, or to go at all. It was no doubt after his grievous illness in March 3020 that his mind was made up.
But you see, she does nothing ¬¬
