“When I say ‘all sentient beings are equal,’ what I mean is that, with respect to any sentient being, we are required to give a compelling moral reason to justify or excuse imposing suffering and death on that being. I maintain that my view here is not only not controversial, but that most people actually agree with it.
What we need to see is that pleasure, amusement, or convenience cannot suffice as ‘compelling moral reasons’ for eating, wearing, or using animals. That necessarily leads us to rule out 99.99% of all animal use as morally unjustifiable from the outset.”
