I don't get why everyone is criticising this story- it just tells what happened to the guy. He's a flesh and blood human being who went through some very tough combat. War is not fun and games, and telling that truthfully is not anti-war propoganda.
The reason people are criticizing this article is because it is a typical example of the biased stuff that comes out of the media:
Example:
"Before long, he began working in a body shop, where the owner told him the most extraordinary thing: Miller could get his auto body repair certification for free -- just by joining the military. A Marine recruiter offered more: insurance, housing, college money."
That excerpt- "the most extraordinary thing"- just drips of condescension. According to the author, this young man joined the military because he was an illiterate redneck looking to get an auto body repair certificate. The second part of that excerpt- about the Marine recruiter- implies that the Marines recruit by bribing and tricking innocent (illiterate, redneck) youths into joining up.
That's why people are so up-in-arms about the liberal media. They don't often show their bias outright, preferring to make subtle hints and vague remarks intended to undermine politicians and institutions they don't agree with.
