Arab fundamentalists VS the rest of the world.

Arab Muslims are not the only immigrant faith in the west.But if the resources of the western governments are frittered away in just quelling and placating Muslim medieval sensibilities then development and humanitarian work for native and the rest of the population will get affected. Does placating Muslim sensibilities too much at the expense of other faith ,dilute the secular and open societies of the west? Is the nuisance and mayhem creating possibility of a certain section of Muslim immigrants in the west call for stringent examination of psychological make up of future Muslim immigration anywhere in the world?Since when mass beheading is an acceptable form of punishment? Where is the outrage against Christian persecution by Muslims?
