Princess Diana
Just this thread reminds me of her, as one of her boyfriends after her divorce from Prince Charles was Hasknat Khan, originally from Pakistan. She fell in love with him, and tried to learn about Islam and what it means.
He was a heart surgeon. She even went to his homeland and met his family.
Recall that India was partitioned into Pakistan (muslim) and India (predominately hindu) by the British. That was a bit of a disaster. Previously they had lived somewhat peacefully in one nation. Thing is, like it or not, we live in a multicultural world, a pluralistic globalised society. We can now choose which religion (or none) to affiliate with. That is a luxury no previous generations ever had before.
'Western' world isn't soley confined to Christendom anymore. As Christians we must face this fact, and not be alarmed that there are people from *gasp* other religions and not all of them are hell-bent on world domination.
