11/9/09 Addendum: I read earlier that the average adult male body contains 6 quarts of blood. Round that down to five quarts to account for women and children and recall that there are four quarts in a gallon, and you\’ve got approximately 327,500,000 gallons of blood spilled by democidal mortacracies in the twentieth century. By comparison, wikipedia reports that the capacity of the Exxon Valdez was roughly 53 million gallons. The Valdez spilled some 10.8 million gallons of crude oil into Prince William Sound in the one of the biggest environmental disasters on record. Thus, a crude estimate suggests that the blood spilled by democide in the 20th century would fill over six tankers with the capacity of the Exxon Valdez.
