Mike, well funnily enough I *have* used christian in an offensive way - when calling a Pagan friend of mine "christian" (as in someone who behaves in a kind and giving fashion), she was most put out about it too!!

But unfortunately I feel the particular use and indeed general understanding of that term, seems to be falling into dis-use. Perhaps it's an anachronism in our multi-faith world, yet as I adored Bunyan as a child - I think (as well as being a bit of a hippy) I'm a little 'quaint' or indeed old fashioned in some areas.
