Some people get all warm and fuzzy when they hear that phrase, while others are realistic or skeptical enough to see through it. It's a tradeoff, and I guess they had to decide who they wanted to appeal to more.
I would think that many of the religious, if they are in the know, would themselves cringe at the claim. The WTC bombing was in their back yard, for heaven's sake. Kumbaya to Islam will only get you killed in the long run. Even Kumbaya to Unitarians is dangerous because it will fill your society with new age rot.
