Funny, I used to work in the same organisation as a woman who wore a niqab. Not only did she talk to me, she actually hugged me on one occasion as a sign of friendship. (I must admit I was taken aback, but that was my prejudice)
Well over 90% of Muslims, Jews, Christians, Hindus, Buddhists and Atheists just want to live their lives in peace, enjoy their hobbies and their families, celebrate their festivals, fall in love, marry, have kids and die in their beds.
It's always the minority of extremists and bigots who are the problem. The people who want everyone to be exactly like them, think like them, whatever. I know it's more challenging to live in a mixed society than one where everyone is C of E and white, but that's what we have. We either make it work or we have endless conflict and hatred.
