A useful meme for ideological bloggers

I think it would be useful to list the downsides of your own ideology, specifically, who would be hurt if all of one's policy ideas would be enacted. I don't mean the left saying that rich people wouldn't like paying their fair share of taxes, or social conservatives saying that adulters wouldn't like jail (or whatever), but more along the lines of the isolationist saying that tens of thousands of Iraqis would be killed if there were an immediate pullout from Iraq.

I'll have my list soon. I dub the meme "Napoleon's Sink".
