When we have to go to war, then we have to go to war. But there are many former Muslims that would tell you the same thing: we need to open our mouths about the Gospel and let God do the rest.
Are you saved? That is to say, have you asked Jesus to save you? No mean no offense, but you speak as a humanist; as if you have no orientation to a Christian worldview.
Islam is an ideology no different in objective than communism or national socialism. All incompatible with democracy therefor not apples and oranges as I see it. I am not a biblical scholar, but from what I understand Christ was not suicidal or a pacifist.
