People fear difference, whether that is an opinion, race, colour or creed. All religions or branches of religions 'cause a stir' whether it is the death of a pregnant woman in Catholic Ireland who was denied an abortion because of the 'law'. Hardly the sign of an integrated society. Or whether it is the anti abortion religious people in the USA with their terror tactics against doctors, nurses and other health workers. Hardly the sign of 'integration'.
Britain isn't doing too well and there are those that want to blame others for those problems, whether it be Poles, Muslims, unions, people claiming benefits, global warming etc.. In fact the state religion in this country the C of E and the Catholic church are doing there bit with food banks to help the poor, something Hindus, Sikhs and Muslims are also doing and have been doing for a very long time in this country.
Some Muslims are causing a 'stir' in the world, Egypt and Turkey, because they no long want to be ruled in the old way or pushed in a direction against secularism. They feel their time has come to take back what is rightfully theirs, and be able to decide how they are governed without interference from outside, like the anti colonial struggles of yesteryear.
