In a hypothetical situation I am a vegan talking to a meat eater who buys his meat from a supermarket and has no interest in where it came from. I say that I don't think people have the right to eat meat unless they are willing to learn about what it takes to provide that meat, witness it first hand or even produce it for themselves. He says that he doesn't want to know where it came from and is quite happy for someone else to do the dirty work if they are happy to and does not feel at all guilty. Is he morally wrong and do I have a valid argument?
