thats because Westerners don't act out of Christianity, but out of fustration because someone else is impacting their lives in the name of a foreign religion and culture. I believe that the west has abandoned religion to the degree that Muslims still practice it, such as believing in the words of the Bible as being those of God, or whatever. That is now gone. There has been an upshoot of religious fanatism in the southern USA, but that has its roots in another issue. So when Western people's "space' is being pushed by another culture with completely foreign values, norms and beliefs, in their own country, these things happen. It is basic sociology and criminology.
What would happen if western women moved into a muslim neighbourhood, and only wore bikinis in public, because their tribal and religions beliefs told them to absolutely do so. What would happen then?
I am not voicing a personal opinion here, as I really don't have one, I am very neutral on this issue, but it does explain a lot of angst that western people feel now that they are living with many new muslim people who have lately moved into their neighbourhoods....I think its rather obvious, don't you?
