I mean, yeah, you're coming to a small community of LOTR fans and accusing the author of their fandom of being racist. I'm not sure what you expect lol.

But yeah there are some dubiously racist characterizations in the novels. There are also some moments of reflection, like Sam seeing the dead Harad soldier:

He was glad that he could not see the dead face. He wondered what the man's name was and where he came from; and if he was really evil of heart, or what lies or threats had led him on the long march from his home.

I mean, the book is written from a Western POV, and by a white Catholic guy who was born in the late 1800s. I think the chances were pretty slim of him having a modern outlook on race, gender, sexuality, etc.

Edit: omg on midwest.social too hahaha
