Basically what the article says is this: since each culture has a different set of values, each culture has to be viewed according to its own values. Or, as various BB posters are fond of saying: "you can't say that one culture is better than another culture, because you can't judge one culture by another culture's values".
For example, the Western World values equality between the sexes. Therefore, in the Western World, discriminating against women in the workplace is wrong . In many parts of the Third World, on the other hand, men are considered inherently superior to women, and therefore, in accordance with the values of these societies, men are afforded far more rights. Hence, in certain societies, discriminating against women in the workplace is right .
The example of women’s rights is the one given most often, for some reason. It isn't just work inequity, dress codes, and inheritance laws, either. I've seen relativists excuse gang rape and murder in the name of family honour, using arguments that are perfectly reasonable within the framework of moral and/or cultural relativism (I'm still not entirely sure which is which). However, in certain circles, if you say that a brother shouldn't be allowed to murder his sister just because she dishonoured the family name by allowing herself to be raped (since in these societies women are deemed "impure" and it is therefore assumed that if a woman was raped then she must have done something to "invite" it) you run the risk of being accused of cultural insensitivity, or even the dreaded CULTURAL IMPERIALISM ! (TM).
The problem becomes even deeper when we try to apply relativistic principles to slavery and genocide. Can we really say that slavery is unequivocally wrong when Sudanese Muslims believe with all their hearts that enslavement of Sudanese non-Muslims is right ? Can we really say that genocide is always wrong when Nazi ideology and values held that genocide of certain nations was right ?
Common sense tells us that the answer to both of those questions is "yes, we can say that slavery and genocide are wrong ". However, if we look at these questions from a Relativistic POV, and are not hypocritical, we have to conclude that under certain circumstances slavery and genocide are right .
That's the problem in a nutshell. Cultural relativism is a nice theory, and it gives us a pretty good tool with which to understand other cultures, but it's useless in practice, since it doesn't work in a common sense situation (personally I'm in favour of the notion that holds that just because you understand a culture doesn't mean you can't condemn certain aspects of it).
Another problem is that of separating cultural relativism from moral relativism. I'm almost certain that originally cultural relativism had very little to do with morality, but over time they seem to have become entwined, and now it's very hard to tell them apart. I think that one way to solve this problem might be to figure out how they each came about, and what they meant originally. Cultural relativism is easy: Franz Boas coined the term early in the twentieth century while working with Native Americans, and from what I understand he was influenced by German Romantic notions of each nation having a unique creative spirit, or something like that. Moral relativism is more difficult to trace.
