Well, he's a little late to the party. Every other pseudo-religious nutsack, including the benevolent head-sawers from the Religion of Peace, has already proclaimed Katrina to be God's punishment. One guy even claimed that it because the gays were having some kind of street orgy or something in NOLA for Labor Day weekend. Which of course begged the question - if God's intention was to smite the sodomites, shouldn't He have waited until they were actually in town before sending the hurricane?
They certainly aren't Christians. All this time they have been calling Him God, but in reality they have been worshipping Allah along with the other death cultists in the Religion of Peace (TM).
It would sound completely in character to hear these things - about thousands of Americans deserving death on 9/11, or from Katrina or another natural disaster - coming from the mouth of an Imam. If you can see or hear no difference, there IS no difference, lipservice to Jesus notwithstanding.
