I found this link over at Good As You, which reports some religious leaders claiming that it was God who “washed” the sin from New Orleans. One pastor is quoted as saying:
New Orleans now is abortion free. New Orleans now is Mardi Gras free. New Orleans now is free of Southern Decadence and the sodomites, the witchcraft workers, false religion — it's free of all of those things now.” God simply, I believe, in His mercy purged all of that stuff out of there — and now we're going to start over again.
Um, he forgot the mention that it's also now religion-free, as there were quite a number of church buildings that were destroyed as a result of the effects of Katrina. (Of course, he is one of those nutters who pickets abortion clinics, so it's not difficult to figure out what drives his hate.)
