Sometimes we need to admit that some  beliefs are not compatible with the West.    Certain part of the world are still living in the middle ages where they believe in slavery and women as possessions.  What we fail to understand is that that particular belief system never stopped their expansion but it was only slowed down  a few century ago.  The west  almost lost with the fall of the  Eastern Roman Empire,  Greece was under the Ottoman Empire  4 centuries and that not far from  Italy.  Spain was also Isamic and if you study that , it meant Europe was being squeezed on two sides.  It was Germany, Spain,France ,  Poland that stood against the complete fall of the Christianity and the evolution of our western values.   Look at the world map, see that islam have made its way into  Indonesia, Malasia,  Philippines and India.  The spread contiued in the Philippine Island until the Spain put a stop to it.  The spread into North America will create divisions where peace exist
