When I read it, early in the morning, there were over 4000 comments on the thing, 98% of which were people howling at how stupid the thing was. It was patently obvious to the common folk that Islam was the motive. The chasm between right-thinking people and the dimwitted brutes that make up the bulk of America was huge.
One of the idiots in the comment thread even had the gall to link to the Koran, Chapter 47 which contains this. The payoff comes near the end, in italics and bold from yours truly. Think about what it means.
47:1 Those who disbelieve and turn (men) from Allah’s way, He will destroy their works.
47:2 And those who believe and do good, and believe in that which has been revealed to Muhammad — and it is the Truth from their Lord — He will remove their evil from them and improve their condition.
47:3 That is because those who disbelieve follow falsehood, and those who believe follow the Truth from their Lord. Thus does Allah set forth their descriptions for men.
47:4 So when you meet in battle those who disbelieve, smite the necks; then, when you have overcome them, make (them) prisoners, and afterwards (set them free) as a favour or for ransom till the war lay down its burdens. That (shall be so). And if Allah please, He would certainly exact retribution from them, but that He may try some of you by means of others. And those who are slain in the way of Allah, He will never allow their deeds to perish.
47:5 He will guide them and improve their condition.
47:6 And make them enter the Garden, which He has made known to them.
47:7 O you who believe, if you help Allah, He will help you and make firm your feet.
47:8 And those who disbelieve, for them is destruction, and He will destroy their works.
47:9 That is because they hate that which Allah reveals, so He has rendered their deeds fruitless.
