That hardly fits the criteria, if at all.
LotR is a relatively straightforward fantasy story where the evil side is mostly composed by monsters. Most fiction with monsters doesn't bother with creating nuance where monsters can be innocent too and should have rights. This is hardly exclusive to western fiction (let's ignore that he talks about english books as american ones). Ghibli works are a rare (and commendable) exception.
About the Haradrim, which, afaik are the only humans in Sauron's service, or at least the most relevant ones, they were corrupted by Sauron, but this quote from Sam certainly adds nuance to the situation, implying it isn't as simple as "they're all evil and bloodthirsty":
"It was Sam's first view of a battle of Men against Men, and he did not like it much. 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; and if he would rather have stayed there in peace."
I'm no Tolkien scholar though and there's already a thread on Era discussing these issues in his work and it certainly is a discussion worth having.
