We are delighted if anyone of any religion - or indeed no religion - wants to start or join a debate on the forums. But it's worth reading our netiquette guide - specifically this:
Religion & Spirituality
We have a forum for this and we welcome posts on all religions and none. We are, though, a discussion forum, not a site for sermons.
I've thought about this some more. The general feeling at GNHQ (and elsewhere) would seem to be that Christians don't mind their religion being made fun of, but other faiths do, or might do, so we can't have any of that!
