Well, since this thread seems safely derailed, I'll chip in my two cents.
I personally find both postmodernism, and especially the relativistic ideas therein, and objectivism to be equally silly. About the only thing sillier is the idea that one faces a dilemma in choosing between them. On a simple level, you can have more than one "good" without eliminating the concept of "bad".
Take, for example, a q150 axe, a q100 hammer, and a q10 wedge of generic gouda. The axe and the hammer are both good things, but they are not the same, and can't be used in the same way. The gouda, on the other hand, is a waste of the labor and materials that went into it. If the gouda is not precisely "bad", we can at least argue that it is unquestionably worse than the others. Only a ravening relativist would argue with that. (I await your flames, oh ravening relatavists

)
Or for a more real-world approach, one can agree that both Japanese and Mexican foods are great, while retaining a preference for one. So if I prefer Mexican food, and my friend says "Japanese food is the best in the world!", I can safely say that I respect his opinion without being accused of intellectual laziness. It is possible to recognize the quality of something for another person without holding that same opinion yourself.
