IMO, a person who goes around barking "nuke mecca" is more dangerous than somebody who goes around saying "Islam means peace" as he simultaneouly attempts to physically remove the radical Islamists from this planet.
Fair enough. Where we disagree is on whom we take seriously. I generally don't believe the "nuke Mecca crowd" is as crazy as has been characterized; I think what we're reading is mainly trash-talking bluster, though they correctly identify Islam as an intransigent foe. In any event, they're powerless.
OTH, those of the "Islam means peace" persuasion do not accept the "Clash of Civilizations" model for the conflict in which we find ourselves, and hold great sway in this Administration. While I have no major complaints with how the War on Terror has been conducted thus far, "Islam means peace" may prove to be problematic as events unfold.
