Is it wrong to feel attached to members of your own ethic group or race? I'd say yes, if that means you don't give other individuals the rights that they deserve.What's so special about people? Well, inherently, nothing, really. But they're members of my own species. Is it wrong to feel attached to members of your own species?
What you do is highly arbitrary: why the species and not the population (race), family, order, class,...? There are so many classifications. And there are other reasons why species boundary is not morally relevant (copy from my website)
Arguments against the species boundary
In order to avoid the risk of opportunism in our ethics, we should avoid adding arbitrary, farfetched or fuzzy criteria without good reasons.
1) The biological species boundary is arbitrary. Why pick out species in the list of biological categories? I belong to the kingdom of animals, the phylum of chordates and vertebrates, the class of mammals, the infraclass of eutheria, the order of primates, the suborder of dry-nosed primates, the infraorder of simians, the superfamily of Hominoidea, the family of great apes, the genus Homo, the speciesHomo sapiens, the subspecies Homo sapiens sapiens and the ethnic group of whites. It is arbitrary to pick out the species. Why adding this arbitrariness in our ethics?
2) The biological definition of species is very complicated and too farfetched to be used in a moral system. One of the many definitions of species refers to the possibility of interbreeding and getting fertile offspring. But why should this possibility be relevant? It is too farfetched to say that a being has rights if its close relatives could have get fertile offspring with some other morally relevant beings. (I refer to its close relatives because the being himself could be infertile.)
3) There is a potential fuzzy boundary: It is not unlikely that a human-chimpansee hybrid (humanzee or chuman) can be born. 10% of mammal species can form interspecies hybrids. We have seen lion-leopards, lion-tigers, camel-lamas, dolphin-killer whales, sheep-goats, grizzly-polar bears and off course horse-donkeys (mules). If these are possible, and if the genetic distance between humans and chimpanzees is not larger than the distance between those existing interbreeding species, it is possible that humanzees can be born. What would the moral status of this hybrid human be? Will it get rights? Also here there is an arbitrariness.
4) Species boundary refers to genes or appearance, and these are not morally relevant because there is no such a thing as an interest gene connected to all and only humans. Or in other words, there is no essence related to a species.
Arguments in favor of sentience
Each normative ethical system implies an argument for sentience. All the four arguments below have the same structure: starting with two assumptions (on fact and one value statement) one can derive that sentience is morally relevant
1) Virtue ethics and ethics of care
Fact: We can feel empathy in a meaningful way with all and only sentient beings (beings who can feel and have a well-being).
Value: Developing the virtue of empathy is good and important.
2) Welfare ethics (consequentialism) and fairness ethics (contractarianism):
Fact: Our own well-being matters to us.
Value: Impartiality is important. There is a thought experiment to check impartiality: imagine that you might be any other object or being, but you dont know who or what you might be. You can be a non-sentient object without well-being, or a sentient being. How would you like to be treated? Sentience will imply a different treatment.
3) Rights ethics (deontologism):
Fact: a sentient being is a being that has interests and can subjectively feel its interests.
Value: protection of interests by respecting rights is important. Note that rights are tools to protect interests. So the coupling sentience interests rights is not farfetched.
4) Other ethics:
Fact: a consciousness is something very complex, vulnerable and unique in the universe.
Value: We should protect and respect something vulnerable, complex or unique. Having a consciousness is something much more remarkable than having the genes of an arbitrary species.
