Peter Jackson did a lot of the damage here. That and the extended mythology being spread across the silmarillion and like 12 other super long books of drafts and notes and letters etc. However, the first and second age both show that these Men Of the West kinda fucking suck. Even prior to Sauron getting involved the Numenoreans were brutal colonists, displacing people and then absolutely devastating the area via resource extraction, mostly to build more ships to do more colonizing. The people they fucked over were even technically on the same level as them in their own invented race hierarchy. A decent amount of the elves also fucking suck and based on the very sparse physical descriptions they dont look nearly as aryan as the movies and generally dont view themselves as our superiors with a few notable exceptions. Orcs are corrupted but not inherently evil, they're basically slaves to whatever dark lord is going on at the time and are killed on site by most other people, Tolkien struggled with this himself but for the first age youre more or less under the literal control of an evil god and then for the next 30 000 years or so every non orc has been out to kill you, it makes prettt good sense to me the feeling would be mutual by now. My dude Ghan-Bury-Ghan in Return of the King talks about how the people of Rohan hunt his people. The dwarves generally come off okay, but the elves were mostly assholes until the 2nd age where there bullshit had almost destroyed the earth and they decided to chill a little, the Numenoreans were pricks and the Dunedain inherited their colonies. Supporting Franco is still fucking bad but like any other comment Tolkien ever made on contemporary issues, he's an incoherent dumbass. Dude was an anarcho monarchist.
