You never know what will set off all the emailers with itchy send-fingers. Some are objecting to what they conclude is my injection of a bizarre Revelation-styled Christian Armageddon into the discussion through my link to the Four Horsemen. To which I say: settle down people. I was simply referring to the historical realities of war, pestilence, famine (scarcity), and death — all nicely imagined as Four Horsemen in apocalyptic literature. Some quick googling shows that I am not the first to make this suggestion.
