Study the habits of other animals (even our closest cousins like mammals) and you'll see a lot of behavior that is unfathomable to humans; dolphins who use sex to assert dominance, mother cats who let a sickly kitten starve, ducks who will engage in necrophilia. If we created fantasy races with similar traits (dwarves use sex to assert dominance, elves let a sickly child starve, or gnomes who engage in necrophilia) we wouldn't be able to identify with or accept these as acceptable traits, even though such traits do exist in those animals and it hasn't stopped people from loving dolphins, cats, or ducks.
Even still, these aren't entirely unfathomable traits, you can find many of them in humans to some degree and it is the power of our ration and irrational mind that we are able to stop and look at these traits and say: I understand using sex as a method of dominance, even though I do not approve of people who do so.
Adding a single trait to a non-human species wouldn't make the race so unfathomable as to make the reader unable to connect, but adding enough of them as to make a non-human completely inhuman would.
I mean, imagine a race of elves who use sex to assert dominance to the point where if anyone misbehaves publicly, forcible sex is the manner in which they're punished. While at the same time, the weak are considered beneath their concerns to the point where they're not even fed, even if they break the law to feed themselves, they're not even punished by sex, it's like a stray animal stealing food to stay alive, they see it as that creature attempting to demonstrate its strength towards others, its will to survive. And the only way for these weaklings to exert dominance truly is of course, in a sexual manner but the only members of society truly weaker than them are the dead, so they specifically target the dead of the rich and powerful as a way to demonstrate dominance over the still living members of that family.
Yes, that's incredibly disturbing. There's no way in hell I'd allow a person to play that, much less even have it exist in my game because it is so outrightly disgusting that I barely want to read what I just wrote.
And that's exactly my secondary point: if you attempt to create something so inhuman such as that, you cause the reader to be so repulsed, so angered by what they are reading that they STOP READING. So writing something "human-but-different" is preferable to writing something "alien" because the simple fact of the manner is that people won't even bother with "alienisms".
