I'd say these "what to name X" questions are a bit of a gamble on the part of the querent. JBH & a CVn (I think, in this case rightly) says they're off-topic. Way too much room for divergent opinion. Even for my taste, and I am generally one who votes to keep "opinion based" queries open, simply because they're good worldbuilding questions.
As for the above specific example, I personally don't follow E.SE, so would never have seen the query. Given the nature of the query as being fundamentally fantasy or sci-fi related, I think WB.SE is as good a place to ask the question as any. Furthermore, if someone flagged the query for closure, I'd vote to keep it open.
In rereading the query, I come across very many perfectly fine and acceptable answers. But --- and I am not saying this because I wrote the response! --- the one answer that truly ties together the OP's fantasy/sci-fi perspective with the broader genre of literature was "sophont rights".
Would that have been given as an in-genre answer in E.SE? Possibly. But the fact that the OP chose a Stack that corresponded more closely with Sci-Fi and Fantasy as a genre I think lead to a much more appropriate array of answers. After all, on E.SE, I would expect either some kind of legal term or some kind of synonym picked out of the thesaurus. Whereas on WB.SE, I would expect an answer that takes into account creative worldbuilding and its associated genres of literature.
As for your question about "humane"; I think your best bet would be to kick it around in the Sandbox (sorry I don't have a link!) and see what people think before deciding whether to post or not.
As I look through the etymology of the word I can clearly see why you would want to ask that question. And given the success of "human rights" in a (truly) polyracial society, I can see why you might want to ask it here rather than on English.SE.
If you choose to ask it, I can say that I'll have an answer!
