A "phobia" is an irrational fear. The worldwide Islamic community has demonstrated emphatically that it is a breeding ground for extremism, coupled with distrust, hate, and homicidal sentiments against not only non-Muslims, but Muslims who profess slightly different versions of Islam. It is not irrational for The Western World to take precautions against being victimized, and if some innocent Muslims are inconvenienced or rejected in our attempt to make ourselves safe, that is an acceptable collateral happening. Why are 70% of the Syrian refugees entering Europe young-adult males? It gives one pause.
While Islam claims to be peaceful and hospitable, one cannot fail to notice that the millions of Muslim refugees (starting with the "Palestinian" refugees fleeing Israel in the late 40's) are NEVER taken in by Islamic countries, and they INVARIABLY seek to settle in Western countries where they are a small minority. Is this because they want to embrace the joys of being German, or French, or British? It does not appear so.
In fact, Islam is not a "religion" as that term is understood in Western culture. "Separation of Church and State" is absurd in Islam; Islam is a comprehensive "rule book" for life that demands physical enforcement and hence, the dominance of government (in Islamic countries) by Islam and its leaders. In Iran, for example, every action by the elected political leaders and bodies is subject to being overturned by the chief imam. Even "moderate" Muslims around the world, when speaking truthfully, all support the concept of Sharia law - along with the enforcement that goes with it.
