Shut the fuck up.
Each life is worth one life. It's not like an Iraqi life is worth more than an American life just because there are fewer of them. Thinking of people as part of a collective is about 99% of why the world is SO fucked up. The people who write that crap deserve to be hit in the head with a crowbar and told "That's, proportionally, like me hitting one retarded person with a crowbar."
If I go to Luxembourg and kick some shithead in the balls that's not the same as kicking 621 Americans in the balls. For me to do that I have to go up to 621 INDIVIDUAL Americans and kick them in the balls. It's not DIFFICULT math.
