Same answer as before, Jim. We want to reduce the incidences of this crime. If we can identify any group that can influence that reduction, we should do so. It is not in my mind anything to do with labelling the crime but is all about looking for leaders who can assist in preventing it. So of your categories 'Christian' might have some value, because we could in principle persuade the various leaders to put pressure on their subordinates to do something to reduce it. There are no relevant leaders for 'white' or 'Anglo-Saxon' that I can see. For 'British' you have Parliament in general, so that is more or less covered, at least in theory.

Putting labels on anything has no inherent value. It is how you then use the label that matters, and in particular whether the label enhances your understanding of the issues or makes you ignore aspects of it. So I don't have any issue with saying that this crime is more common amongst the XXX-group than elsewhere; but I have a serious problem if that is taken as we need only address the XXX portion.
