The Quran is often misinterpreted and misunderstood. Which is why you will see many misguided Muslims in the world today. Our Prophet himself said that Muslims will divide into more sects than even Christians and Jews!
As for me I have always found my non Muslim mates and associates to be very respectful of my religion. In fact I remember the first time when I got into the abayah my own family was so insulting towards me where else my Buddhist former classmate went out and bought me appropriate clothes to wear under my abayah so I will be comfortable! My husbands mom was here in Qatar for two months and she was so impressed with our way of life and how we took care of her that she is now considering becoming a Muslim. This I believe is the true essence of our faith, whereby we draw people to it rather than turning others away from it!
