I guess it ends here then, because I would regard myself as a moderate anthropocentrist (not religious though): humanity is more valuable (to humans) than any other race, whereas you seem to be egalitarian or biocentrist. Ironically, your statement that morals and rights should extend equally to all other races is in itself extremely anthropocentric, because you believe that just because we humans have a perception of what is right and wrong, what is good or evil, means that this thinking extends to everything else, when, in fact, any alien species may have an entirely different perception of morality that rivals our own. What is to say that theirs is inferior?
What you regard as right and wrong, is very much based on genetical heritage. A human has a genetically built basis (the moral center in the brain) from which our later advanced thoughts are constructed. What is to say that an alien species will have the same moral center, if any? Are their morals, or, lack thereof, therefore inferior? If we do not allow ourselves to regard the value of a human as more than that of any other animal or race, then we may as well equal a human with any other animal or race (else we would be favouring an organism over another!), and the outcome of that would be catastrophic.
