Here's what I posted in Michael's comments:
From my hobby horse, blaming Infinity Ward for this callousness is like blaming the homeric bards for the graphic violence and smacktalk of their battles. By doing that kind of blaming, we certainly assert our own superiority (which is not an unimportant thing to do). But we also start from a position of having missed something that's culturally interesting about the game and its marketing. You catch precisely that interesting facet here.
