well we should all have our own seperate rights, since certain speciecs even though sentient maybe have a different culture/view on death/re-production ect ect. for instance lets say that mating for that species is basically random alien walks up to random aliens girl and they just do what ever they do to re-produce, the female (if there is a female for said species) has no choice, this would probably be considered rape (in AMERICAAAA) so we would say its against the law, forcing that species to leave or change there way of re-production entirely, aliens should have alien rights, not human rights, infact, could each species just have there own worlds?? kind of like mass effects...
