Foer: Sometimes, there’s an inversion of values in the language, like “Make America Great Again.” If we could only return to being something that we never were, then we will reclaim a kind of pride. We’ve always been a country that cares about farmers and animals in a way that’s unusual in the world. I think a lot of it is religious values — ideas of dominion over animals and the planet. Factory farming is a perversion of those values, and a movement away from factory farming is a return to those values. Even though it often sounds like vegetarianism is some newfangled, hippie-ish, kind of progressive thing, it’s actually conservative. That’s, in a way, the joke behind all of this.
