There are a lot more white people than Muslims but I don't hear anyone saying there's too many of them.
One of my closest friends is a Muslim who is now an immigration counsellor to help Muslims immigrate to Canada, I grew up in and travelled to Muslim countries (North Africa, Mid-East) so I know the Muslim culture very very well. Our annual xmas dinner is couscous. We also have many many Muslim friends of the family. They are some of the hardest working kindest people I have ever met.
Yes, some Muslims are problematic but so are some whites, blacks, Chinese, christians, so on and so forth. There are always some bad apples in every group.
I remember reading an article in the New York Times in which a group of black New Yorkers said that after 9/11, racism shifted from them to the Muslims. They said and I quote: "Muslims are the new Blacks."
