"Relative" Morality--an Oxymoron

The philosopher Alasdair MacIntyre delves into this problem in his seminal book After Virtue:

“In a famous passage in The Gay Science (section 335) Nietzsche jeers at the notion of basing morality on inner moral sentiments, on conscience, on the one hand, or on the Kantian categorical imperative, on universalizability, on the other. In five swift, witty and cogent paragraphs he disposes of both what I have called the Enlightenment project to discover rational foundations for an objective morality and of the confidence of the everyday moral agent in post-Enlightenment culture that his moral practice and utterance are in good order. But Nietzsche then goes on to confront the problem that this act of destruction has created. The underlying structure of his argument is as follows: if there is nothing to morality but expressions of will, my morality can only be what my will creates. There can be no place for such fictions as natural rights, utility, the greatest happiness of the greatest number. I myself must now bring into existence ‘new tables of what is good’.”
