So, I admire Tolkiens work, huge lore which he created with attention to details.
However, as much as I envy his work, there was always one thing that kept irritating me while reading LOTR, Silmarillion and other Tolkiens works.
West vs East.
For some reason Tolkien focused a lot on depicting west as chivalric, good-natured, full of love and courage while depicting east as barbaric, cruel and fusty. Of course this is oversimplification and there were exceptions, but the general rule stands. I never understood emphasis which he put on this.
I understand that this might be a result from his war experience, as well as worlds division between capitalist and communist during his life.
In this manner you can say that Mordor is a hybrid of nazi Germany and USRR. But this is only one small example. Virtually all eastern civilisations in his uninverse are inferior to western counterparts.
So, here is a thing to discuss: was Tolkien considering "western" cultures to be superior to "eastern" ones in real world? Was he racist? Or maybe his fictional universe is not a reflection of his real life views at all?
