LotR isnt absolute tho, and explicitly rejects the morals the fash take from it lol. The reality is the fash will take what they like and coopt it (if they even read the book—my impression is most right wing engagement is with the whitewashed jackson movies)

Tolkien actually has a letter talking about this absolutist interpretation and how untrue it is:

That second last sentence in particular is key: we do not see the civilians of the East or South, their regular people. We see their soldiers who are allied with Sauron to wage a war for global domination. We see, repeatedly, that some of these soldiers (orcs included) have mixed feelings—but not so much as to lead them to desert or question bad or evil orders; much like the western soldiers theyre based on.

When enemy soldiers flee, as after the battle at the black gate, they arent chased down and exterminated and, unlike the movies, they dont just dissolve into dust bc, in the books, they are people (albeit extremely warped people, like the British of today). With time for their society to not be a slave-military of sauron, they will likely change.

The closest thing to a pure good LotR has is the Ents (and even they can go rotten!). The closest to a pure evil is Sauron who, again, explicitly, did not start evil and is not "ontologically" evil; he is a powerful being who has chosen to amass power to himself and destroy nature, becoming evil, and constantly choosing to do evil.
