You mean the doctrine that says that not all cultures are equivalent? The doctrine that says that there are such things as good and evil, and that good is worth fighting for, even pre-emptively?
I think it would be a stretch of the imagination for Tolkien himself to come to to that conclusion, but by all means, clue me in. I have always thought it was just a well-written and delightful fantasy classic with a message of good prevailing over evil, or is that your point?
