Here’s the situation: you’re flying over the snowy Alaskan mountains in a twin seater plane, your loved on at the control stick. Your plane goes down, and you survive, but your partner is killed. Dragging yourself to a nearby hunting cabin, you find a shelter with firewood and a potbelly stove, blankets, kitchenwares, and a cupboardful of condiments, herbs, spices and garnishes. While you’re trapped for the time being, you realize that if you survive until the summer, the owner of the cabin will probably return for bear season and rescue you. However, there’s no food around and you’re inept at setting traps for squirrels: you’ll have to eat your loved one to survive until then.
Assuming you choose to live, do you prepare your loved one in a tasty dish, or eat them raw?
Never attribute to an -ism anything more easily exlained by common, human stupidity.
