Yeah, it's happened since Modern Humans/Cro Magnon (EEHM) split. It doesn't matter who or what is right. All that matters is who gets to the write the history at the end.
I want Humans to be writing that history. I don't care and it doesn't matter about Race, Creed, or Wealth. Skin doesn't matter to me at all, Species does. If Aliens come around, they want to start shit, fuck them too. Eat their bodies(if it doesn't kill you), Vegeta and Nappa style. All about the Humans.
