If it adds anything to the discussion --- we had a very good, nice, Muslim Pakistani family at my last school in Bradford. Dad was a senior Dr., can't remember mum's occupation, something to do with law. The daughter I knew and taught was a great kid and she followed her older 2 brothers into a Russell group uni.. (one of them went to, I think, Cambridge) lovely girl, westernised, played hockey etc. for the school.
We were really looking forward to welcoming the younger brother - but dad refused and told us that, as a school, we now had too many of the 'wrong sort of Muslims'. I quote exactly - it stuck in the memory.
I am proud of being a Christian - but it is not our way to flaunt our beliefs, sorry. Perhaps you are right Theland and it is time to be more assertive. I would find this difficult. Where I live assumes that we are all basically Christian. I hope that I would not be found to be wanting if called upon to stand up for my beliefs, but I don't want another 'Holy War'. Different if pushed to the limit.
