I can see how Tolkien’s work might appeal to fascists at a surface-level. There is the racism of one’s bloodline and lineage determining one’s traits, and the portrayal of the Enemy as varieties of the people living to the East and South of Europe. I love Tolkien’s works, but I don’t like any of those elements. For a man born in the late 1800s, his views on race were average – not a virulent, active racism, but a passive, presumptive racism. His imagination was, alas, colonized as well as extraordinary.
But Tolkien hated fascists, and fascism. Not only did his sons risk their lives to fight against it, but in all of his writings, one never finds the slightest tolerance for fascism, and he had a few contemptuous things to say about fascists themselves.
More importantly, I cannot imagine a more thorough condemnation of all forms of authoritarianism than The Lord of the Rings. Gandalf, offered the Ring, which represents coercive power, responds with the appropriate amount of fear and disgust. Galadriel rejects it as well, and by rejecting it at last earns her return to the Blessed Land. She is literally saved by her rejection of authoritarianism, even well-intentioned authoritarianism. Faramir similarly ‘shows his quality’ by refusing the Ring – by refusing coercive power, and by passing the test that his brother failed. (Note that Boromir redeems himself after his failure by giving his life defending those weaker than himself – something a fascist would never do)
What we have is a story where the heroes would rather die, would rather their society collapse into ruin, would rather end, in Aragorn’s case, the thousands of years of Numenor’s legacy in Middle-Earth, than take up the Ring as authoritarians and rule by dominating other people’s wills. They would rather their culture and legacy burn to the ground than take up the Ring, and the put their hope and faith in the weak overcoming the strong.
The position that the heroes, and the Wise, take in the War of the Ring could not be farther from fascism, which is among other things the promise that through authoritarianism, through coercion, society will be saved and made pure. It is an ideology of contempt for those weaker than one’s self. I think that a lifetime spent despising fascism, and the experience of being at war with it in the form of Nazism, definitely shaped Tolkien’s story, and that fascists looking for vindication in Middle-Earth are looking in the wrong place.
