Word for a belief in extra-terrestrial rights

Looking for a word that means, "a belief in goodness and liberty toward sentient aliens." The use of "humanitarian" doesn't seem to fit due to the use of "human" in it, and I am not entirely convinced that "xenotarian" is a valid word (although it might be.)

Closest thing I can think of is xenophilia: http://en.wikipedia.org/wiki/Xenophilia

More generally, allophilia: http://en.wikipedia.org/wiki/Allophilia

"Xenotarian" sounds like a person who only eats aliens, haha.

In Buddhism it is frequently used the expression "sentient beings". Reference I think you could use the same expression.

If you want to emphasize the E.T. nature perhaps you could use the expression "Non-Earthly" as in "...toward all Non-Earthly sentient beings" I don't think there is a single word expression for this.
