I'm a christian but I have read the Quran, it says "if they do not accept their faith, let them go their way, and you go your way, because allah will
judge them even if they do not believe"
stop believing everything on the news
You obviously haven't read the Koran or you would have seen this.
Fighting is prescribed for you, and ye dislike it. But it is possible that ye dislike a thing which is good for you, and that ye love a thing which is bad for you. But God knoweth, and ye know not. (2:216)
But when the forbidden months are past, then fight and slay the pagans wherever ye find them, and seize them, beleaguer them, and lie in wait for them in every stratagem (of war); but if they repent, and establish regular prayers and practice regular charity, then open the way for them: for God is Oft-forgiving, Most Merciful. (9:5)
Fight those who believe not in God nor the Last Day, nor hold that forbidden which hath been forbidden by God and His Apostle, nor acknowledge the religion of Truth, (even if they are) of the People of the Book (Christians and Jews), until they pay the jizya [tribute] with willing submission, and feel themselves subdued. (9:29).
Rudolph Peters, professor of Islamic Law and Law of the Middle East at the University of Amsterdam, observes, “The crux of the doctrine is the existence of one single Islamic state, ruling the entire umma [Muslim community].
It is the duty of the umma to expand the territory of this state in order to bring as many people under its rule as possible.The ultimate aim is to expand the territory of this state in order to bring the whole earth under the sway of Islam and to extirpate unbelief.” Many Muslim scholars also believe that the "sword verses," which came after the verses preaching kindness and peace, cancel out those previous verses.
