What I want to add is that I think that any sort of universal tolerance between cultures has some very undesirable consequences, especially for women and other weaker groups. I think that Ayesha is missing this aspect of things.

If we are universally tolerant of other cultures, we must be tolerant of slavery and clitoridectomy and every other practice sanctioned by some culture.

Think of what that implies! If the Germans had won World War II and Nazism had become an established culture, we would have to be tolerant of its racial practices. I think this amounts to a reductio ad absurdum for any general principle of tolerance between cultures.

Part of the problem here is that many anthropologists once spoke as if all the people within a culture accepted its values. They left no room for oppressed or exploited groups that did not accept the dominant views but were unable to change their situation. Once we recognize that cultures contain groups that do not accept the dominant view, the case for tolerating the dominant view and for not interfering with it is seriously weakened.
