It's funny because Tolkien's entire body of work has always had more to do with the state of the souls of men and their battle with (or acceptance of) darkness than it ever had to do with anything even remotely racial. In acting like beastial demonic savages, niggers and other browns become orcs and Eastern Men. It was never Tolkien 'being racist' and making a fantasy allusion to shitskins.

It's like that Elon meme: Tolkien basically just said "if you act like this, you are an evil savage," and shitlibs said, "how dare you say that about black people!!!"
