I downvoted it because not only is the content stupid, everyone here should already know it's stupid. If the comments tell me anyone would take this argument seriously, I'll change my vote.
I take this argument seriously. I first saw it a year ago, and it caused me to change my behavior.
ETA: I don't take the economics of it seriously. I take seriously the argument that it if is wrong to let someone die whom I could save (and my morality says this), then I ought to give a lot of money to efficient charity.
I'd be really interested to hear what the Less Wrong community thinks of this. Don't spoil it by reading the comments first.
