“We only ever got pig blood. This wasn’t because it was the only type of animal blood the butcher had. “Pigs are dirty,” my mum said once. “It’s what your body deserves.” But it turns out that pigs aren’t naturally dirty. Rather, humans keep pigs in dirty conditions, feeding them rotten vegetables, letting the mud in their too-small pens mix with their feces; the filth of the pig is just symptomatic of the sins of the human.”
