When you compare it to how the others speak and the relevant textual space the Orcs occupy, it does raise an in-universe class dimension, in addition to the purely racial one. You don't even need a sociological reading of the text, that would interrogate its relationship w/ Tolkien's social milieu!

When you read it textually within even the in-text ideas about beauty, purity, pristineness versus corruption, marring, fallenness, you already have something more substantial to say about the ideological position of the text WITHOUT getting into JRRT's biography aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
