Missed an option....

I think this guy doesn't understand logic as much as he thinks. I can come up with at least a couple of different options that he left out:

• God does not always use natural or man-made catastrophes to punish people for moral failings. I don't know if Katrina was the wrath of God. But it's clear that God does not punish every moral failing with a natural disaster. Every human being on the face of the planet has experienced moral failing, yet the vast majority of us survived Katrina. Indeed, most of us survive any natural disaster. It seems pretty evident to me that it's a bad assumption that God always uses natural disasters to punish moral failings.
  
  
• Maybe God did use a natural disaster to destroy Bourbon St. Despite being relatively unscathed Bourbon St. is still in significant trouble. How many customers has it served in the last several days? How long do you think it will be before any of it's services are reopened? Even if this isn't physical destruction, the effects are the same.
