Quran (2:216) - "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 Allah knoweth, and ye know not."
Quran (4:74) - "Let those fight in the way of Allah who sell the life of this world for the other. Whoso fighteth in the way of Allah, be he slain or be he victorious, on him We shall bestow a vast reward."
Quran (5:33)"The punishment of those who wage war against Allah and His messenger and strive to make mischief in the land is only this, that they should be murdered or crucified or their hands and their feet should be cut off on opposite sides or they should be imprisoned; this shall be as a disgrace for them in this world, and in the hereafter they shall have a grievous chastisement"
Quran (8:12) - "I will cast terror into the hearts of those who disbelieve. Therefore strike off their heads and strike off every fingertip of them"
I could go on and on. The sheer number of verses advocating violence and hatred are staggering. You go ahead and have the debate with them about what the Koran really says while they are cutting off your head.
Any rational person knows that certain Muslim groups’ interpretation of the Koran take these passages to mean kill people, and it doesn’t matter what the Koran supposedly or supposedly doesn’t say about peace or what these verses mean– they interpret it their way. Their way means convert or die. Their way means a messianic age can be ushered in by apocalyptic war that destroys the west and subjects everyone to Islam. And there is plenty of historical perspective to back this up.
Lack of facts isn’t our problem here. It’s flagrant disregard of them.
