  Ok, so hypothetically, lets say we made contact with a race from another planet. Not human, eventually, years pass, we would already have new technology. We live with none human intelligent beings.  Would that make all this irrelevant? Our skin?  Cuz now it would be just be between either us humans or them(who or what ever they are).  Sounds crazy, but would something like that change things? For you?   I think that the aliens from outer space would probably be preferable to Jews and Blacks :D
