Viewing from a pessimistic point of view, Tolkien's work can be recognize as racism, as well. With the "evils" in the "wild and unexplored lands of the East" or the Haradrim representing...others...
However, it is pointless, even stupid, to accuse Tolkien of racism, considering the age he lived in.
One would think Elendil's two kingdoms (Arnor and Gondor) are representatives of the two Roman empires.
Shire itself represents Tolkien's ideal "rural Britain." Carefree, ignorant, happy, fertile, but with hidden strength.
The lost Numenor is recognized by many (including Tolkien himself) as an Atlantis of Middle Earth.
