Idiot. He thought he was quoting something nice, but it turns out he was spewing jihadic filth quoted from the Koran!
Ironically, the Qur'anic passage from which his quote comes actually is about fighting unbelievers, and doesn't remotely lead to thoughts of coming together with people with whom one has differences.
In that passage, the Qur'an is scolding Muslims who refused to accompany Muhammad on his expedition to Tabouk in northern Arabia, where he wanted to fight a Byzantine garrison. The Byzantines weren't there when he arrived, and so there was no battle, but he was considerably angered that some Muslims in Medina and among the Bedouins ("wandering Arabs") had refused to make the trip -- they "prefer[red] their lives to his life." The Qur'an promises that if they do anything that "angereth the disbelievers," they will be credited with having done a good deed, and Allah will repay them for such good deeds. The Muslims should fight the unbelievers and be harsh with them.
Obama picked out of this one sentence that made it appear as if the Qur'an was simply counseling one to speak the truth, mindful of the divine presence. In reality, the passage is about the necessity to wage jihad warfare against unbelievers, and not to fail to perform this duty. He took a passage about warfare and division and passed it off as part of a call for us all to come together and sing kumbaya.
And the Left said that Bush was stupid???
It's Obama's turn to be called stupid by the Left and the Old Media.
But of course that ain't happening. The Left and the Old Media don't care how stupid their own folks are!
