I know I'm gonna hear it for this one, but:
Why is that that, whenever anything ill befalls the nation, certain people on the right are prone to say that it's because God is mad at us? Mad for pushing him out of the public square (e.g.: school and government); annoyed at the advancement of gay rights; pissed off at feminists; still ticked that someone somewhen thought that "puce" was a great name for a color; or some other random act of mad-ness directed at the lefties.
Why is it never that God is displeased with the red team? Hurricane Gustav was predicted to come aground almost three years to the day, in pretty nearly the same location as Katrina--guaranteeing that it would interrupt the opening of the Republican Convention. So why wasn't that interpreted as a hint that the Almighty wasn't happy with the way the red team was managing things (including the shameful way in which the Bush administration left New Orleans to its fate three years ago)?
Because that would be stupid. And because you only play the God card when it serves your own purpose or if you're actually dumb enough to think God cares about your football/baseball/hockey/racing team. Oh, wait . . .
