The story behind the game seems to be that two forces are fighting (the Christians vs. the minions of the anti-Christ) and the people you are trying to “win to Jesus” are neutral. I.e., you don’t kill them simply because they don’t convert. The people you fight are the evil minions of the Anti-Christ, who are both trying to kill you and take over the world/subjugate everyone to their sinister yoke. So if you are allowed to fight against anyone, the minions seem like worthy opponents.

That said, I’ve never been much of a fan of apocalyptic fiction, or even trying to figure out what Daniel or the author of Revelation was on about. I figure we’ll see it when it gets here, and wild guesses or fictionalization of the end times will only serve to mislead and confuse.

This is the first I’ve heard of this game, but the hysteria I’ve read about it here, at Pandagon, etc. seems way overblown. In the milieu of the game, the protagonists are fighting against the minions of Darkness, not their intransigent next-door neighbors. Kill the daemonic minions, convert your neighbors. Not exactly a game I’d buy for my kids, but hardly the offense against civilization that some here are making it out to be.

Dispensationalist PreMs expect first the Rapture, then the rise of the AntiChrist through seven years of Tribulation, then Armageddon before Christ returns and brings on the millennium of peace for the born-again before the final judgement. Historical PreMs go for first the Tribulation, with a secret Rapture during the seven years of the Anti-Christ’s rule, with the raptured returning to Earth with Christ to share in the thousand year rule of Heaven.

Postmillennialists believe that the Kingdom of God on Earth has to be established by believers for a thousand years before Christ will return. It’s also split, between Revivalist PostMs (evangelicals) and Reconstructionist PostMs (theocrats).

There seems to be a worrying convergence of theocratic tendencies between the Dispensationalist PreMs and the Reconstructionist PostMs – I guess they figure that whether the Second Coming is before or after the thousand-year Kingdom of Heaven, the theocracy will be the right thing to do for Christ’s return.

In a timely fashion considering Kim’s response to Tim Blair’s baiting about whether progressives would condemn abstinence-only sex-education at a Muslim school in Australia in the same way as when it’s advocated by Christians (yes, of course we woul…

So, it occurs to me that I’ve been writing things like, “We’re on the road to Gilead&# [...]

Note also that simply changing “Christian” to “Muslim” in the above-quoted paragraph would have pundits and lawmakers and a hell of a lot of other people up in arms.
