If I tell you we’re going to the football game and you’re excited for that and then I take you to the ballet instead, it’s still wrong! It’s lying!

We all have the right to feel angry and betrayed when someone we trust lies to us. Vegans don’t have any ethical right to lie to people and most vegans I know are strongly opposed to lying to people about their food.

What if the meat eater has an allergy and now they’re going to the hospital because you lied about the ingredients of the food you served them? If you’re a deontologist then you don’t get to hide behind moral luck here. You’re at fault for the deception regardless of the consequences, just as drunk drivers are at fault regardless of whether or not they hit anyone.
