I have a healthy fear of Islam the political ideology, yes. For very logical and rational reasons. Of course it's easy to be tolerant from half a world away when you have no personal experience of it and the consequences are only rarely felt.
And I wouldn't say muslims fear and hate christians, propaganda about "crusaders" nonwithstanding. They have far more respect for "people of the book" as they call them than secularists, areligious, agnostics, atheists or "pagans". They often have the same views on many social issues after all, especially overlapping on their obsession with controlling sexuality. The muslim counterpart in this scenario would be Occidentalophobic, specifically all "Western" mores and morals not based on religion.
