I followed links to this article in the Nation which reports that a pentagon-approved group is giving soldiers care packages which include the Left Behind video game. Daily Kos and Gameology explain some of the reasons that this is objectionable.
I think as responsible peace-loving Christians, it is important to speak out about how troubling this is. Even fictional stories that portray a violent Christian Crusade against those of other faiths are offensive and dangerous. Giving those materials to American soldiers in a nation populated by muslims invites comparison to other religiously motivated slaughters across history, and it is not flattering for the US or for Christians. I believe all elements of the Left Behind universe are damaging to the civil-religious psyche because of the disturbing masculinist, rambo'd up version of Christianity that they portray. What ever happened to "blessed are the meek?"
(for a more carefully thought out viewpoint about the potential cultural impact of Left Behind, see my friend Kristy Maddux's dissertation.)
