To religious people and nonbelievers who aren’t vegans

To religious people, I’d say treat nonhuman animals the way you would like to be treated by your god or supernatural power, which, for virtually everyone if they’re honest, entails veganism.

To nonbelievers who aren’t vegans, I’d say give your claims to secular morality more thought and importance in your life, because unless you’re vegan, your claim to scientifically-informed, rational, secular morality has a blatant and indefensible absurdity to contend with. The only reason you get away with non-veganism culturally is because you live in a very prejudiced (read: irrational) society when it comes to the moral status of nonhuman animals.
