Eunuchs were given power and influence in Ancient China because they were seen as politically reliable - a eunuch cannot choose his family over his lord if you remove his capacity to have a family. Castration also makes it psychologically difficult for a modern eunuch to abandon the left - to stop being a postmodernist is to admit that he had himself castrated for a lie. Unlike Ancient China the left will not execute a disloyal eunuch, but they will ostracise him to maximise the likelihood that he executes himself.
