Sad thing is, up until katrina they used to play that song at Saints games.
I wouldn't care if the opposing teams play that, its a catchy song.
Now if it said
"Here I am......leave you stranded for days in water, caused by failure of federal levee system. While I put my buddy in charge, and he eats at the best restaurants in Baton Rouge, while no one in New Orleans even has running water. Then take years to give out aid payments. Only to treat you like a red-headed step child. Then blow all our treasury on a war in Iraq."
Then it would be offensive, but that isn't as catchy as "rock you like a hurricane."
Katrina was just a storm, George Bush was a disaster.
