What part of "they were created as a special civilization by the gods" do you not understand? They're biologically indistinct (generally, anyway; the ones in this film have some level of superhuman stamina, but that's probably a god-gifted thing).If they are human, they are NOT supposed to live with one gender, if they are supposed to live as one-gender, they are NOT human.
They're quite human. They have the same fears, hopes, dreams, as other people. They have the key to a cooperative society.Except that they're NOT human, and so have no idea of HUMAN problems. It's easy to talk about respect and cooperation if you're a bunch of genetically engineered freaks designed to have just one culture, no differences.
As non-humans who have no idea how the human mind and world works, they have nothing to teach us.
Your view of societal relations is remarkably narrow, I must say; different species in sci-fi relate and teach each other things all the time, and the difference between Amazon and regular civilization is far less than that.
