I guess a sense of definition is in order here... When I use the word "right" in this sense I mean something aking to an abolute. In this case, if I say I have the right to like and that is "enshined" in Law, then it would be impossible for me to die or be killed. We know however that this is false. Like the rap song says, "people die everyday". On the other hand, I can certainly say that I prefer to live. I can say that with a great degree of certainty.
Thanks (as well) for the comments P. Mason and jpahmad.
