look, the reason MEM is saying katrina was worse is the loss of poor black and homosexual life, which is a huge loss for the democrat party and thus damaging to their elections. the ice storm killed a bunch of white folk, thus high resource users. so their death is actually good for the environment! and honestly, this storm was probably a farewell "fuck you" from the bush administration anyway. so I think we can now understand when MEM says their deaths are the equivalent of him stubbing a toe.
