I remember meeting a girl studying anthropology. She talked about her taking a course on "man eaters". Primitive tribes who occasionally eat people. (Of course it's entirely unacceptable to say "primitive" or even "tribe" in anthropology!) Instead of condemning the practice as morally abhorrent, as they often do, e.g. for persecution of homosexuality, they just talked about why they (the man eaters) do it, what type of spiritual gains they hope to achieve with it, etc, very non-judgmental. On other matters anthropologists are some of the most judgmental people in academia. The absurdity of the double standard was hard to express. Some kind of inconsistent moral relativism.
