It's an interesting question. Would an advanced civilization on an alien planet need an antagonist comparable to the Jews? If their dominant religion wanes, would their equivalent-to-Judaism wax?
Sorry, I don't mean to derail the thread. I'm sure there are transgender aliens, somewhere. We even have 'otherkin' here on the Earth

(NB: my post above: these are the kind of things that were touted as sub-cultures in the 90's, and not gender identifications)
