They mean it, folks. They really mean it:
It’s impossible to overstate the significance of the Death Cultists’ recent, in-your-face brazenness. They think their hour has arrived. They’ve achieved so much, over such a long period, that they’ve come to feel unstoppable. They certainly won’t stop because you dislike the notion of exterminating 94% of Mankind, with the survivors forced to revert to pre-Industrial Revolution standards of living.
I think the point has been adequately established. But for more ammo, get yourself a copy of this little tome. Only $0.99, don’t y’know. “Makes a fine Christmas gift!”
