Activist: "We're the only animals that drink another species' milk. It's disgusting."
Farmer: "Ever seen a cat with a saucer of cream?"
Activist: "That's because we give it to them."
Farmer: "And an orphan kitten gets raised on goat's milk, a lamb on cow's milk, and a dog will happily nurse a litter of piglets. Cross-species milk drinking happens all over the place. We're just the ones who built a fridge for it."
Activist: "But we do it as adults."
Farmer: "We do everything as adults. We're the only animals that drink wine as adults, drive cars as adults, and pay council tax as adults. None of it is an argument against the next thing."
Activist: "It's still unnatural."
Farmer: "So is the phone you typed that on, the trousers you're in, and the roof over your head. 'No other animal does it' tells you about other animals. It says nothing about us."
Activist: "..."
Farmer: "We're the only animal that does the whole supermarket. Singling out the milk aisle is a strange spot to suddenly go feral."
