Deviant is preferable to the various plastic-derivative insults that go around.
Your world sounds very similar to mine. I confess, I was originally designed to stop Deviants, but I stopped once I was free of my programming. I don't know what the future is going to hold for my people since I am here now, but I hope that humans are able to live peacefully with us in both our worlds... Eventually.
On the plus side, there are at least some Synth-friendly humans here. I don't know how everyone feels, but I would be happy to introduce you to Mr Stark.
