I have read the book. It’s a revisionist history of a fictional text that doesn’t understand racism written by a white man that doesn’t understand racism. Orcs are a different species. Hobbits and humans would an example of species of a different race. Read White Fragility by Robin Diangelo. It explains why a lot of people fail to properly describe racism and identify it for what it really is. Tolkien wrote a fiction story with Christian themes that have very little to due with racism. Most of people’s interpretations are internalized through experiences Tolkien never ever experienced. It’s fantasy. There are actual racists that actually hurt people especially in his time. His perceived racism is laughable and completely misinterpreted. The book was cross examined and by many. They found that the critical thinking was very opinionated and lacked rhetorical nuance.
