you just said it makes no difference to them whether they have rights or not in this world. its more important to you than to them . I assume this is because its important to you on their behalf. yet they don’t have a behalf…
I think that we should change the statement to “Animals will have rights when they start to argue.”
We recognize that all humans have rights because we know that humans have the capacity to argue. By engaging in argumentation, instead of using coercion, we presuppose that the other person has self-ownership rights AND, more importantly, that they are going to respect our self-ownership rights.
