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.
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 ¬¬
