Well, as much as some folks want to see it that way, War is no video game. It is not as simple as a sports event ("We kicked some butt in Afghanistan or Iraq"). Real fathers, mothers, sons, sisters are killed. Real limbs are lost. Real blood (American or Iraqi) is spilled. The hatred for the perpetrator of the death of a loved one is as intense on either side.
That is why so many people were angered to see the coffins of the American soldiers. That is why so many people are angered at Michael Moore. Because he is showing the people things that are uncomfortable to see or know.
Believe me. The images in Fahrenheit 911, are nothing compared to the real horror. I would post the link to a site with real war images, but last time I did, some people freaked out so much they started a thread on whether those kind of sites should be banned.
