I don't see it as bashing Tolkien per se, but as pointing out the dark side of nostalgic fantasy. Tolkien's fiction is wonderful to read, but it can also be deconstructed pretty brutally.
There's an author who did the ultimate in this area. He told the story from Mordor's point of view:

A similar deconstruction can be carried out in the real world against, for example, the nostalgic hipsterism of people like James Howard Kunstler. I actually agree with many of Kunstler's aesthetic criticisms of suburbia, but if you dig deeply into his corpus you find a strong thread of reactionary elitism -- what I call a "white pastoral fantasy" set in an imaginary past.
Of course nostalgic fantasy isn't the only thing you can deconstruct... "progress" oriented sci-fi like Star Trek can also be turned upside down. A friend of mine sort of popped that bubble long ago when he pointed out that Star Trek is exclusively told from the point of view of military starships with world-destroying weapons. Think that might be a biased perspective? Would the "Singapore in space" federation really be a good place to live? Ever notice that there's basically no culture, music, or art?
