Well some of the founders of the civil rights movement such as Martin Lutur King jr were from religious organisations and also certain black churches help organised the protests for civil rights. Same with Poland as some of the prominent anti commmunists were members of the church as well as priests that rallied against the communists there. So there has been an positive aspects or religioius organisations that have impacted those societies yet of course the US south and Poland have been more religious than most other western socities. Within Islam not all muslims are alike and many that come to the west come to escape the persecutions of their homelands and many dont want shirah law. Muslims are the most obvious religious group in the west as the women wear hijabs and I see it an great deal in the city where I live. I dont care what people where due to their religous requirements. Of course you get those with extremist beliefs yet those with extremist views are only an minority of that religion.
