So... you are talking about preferences that &#x27;define a human being&#x27;, but then those preferences are only tautologically universal (since you are excluding any possible exception). This seems absurd.<p>So if I were to tell you that I really did prefer to be a slave you would say I am not human? You are excluding as &#x27;human&#x27; any individual who are not capable of understanding the concept of &#x27;ownership&#x27;. Do you seriously believe that babies and the severely mentally handicapped are not human?<p>If you are operating with such a divergent notion of &#x27;human&#x27; (and thus &#x27;morality&#x27;, &#x27;universal&#x27; and &#x27;preference&#x27;) then there is no point in having any further discussion with you or considering anything you have to say.
