Hey, it's just a story. Who cares if it really could have happened. It didn't, and that world will never be. If the massacres, the diseases, the denial of humanity to the survivors had never happened, you and I would not be sitting comfy in our toasty warm homes, with our sense of superiority, voting for the next bunch of thieves, just like us, scrabbling for whatever advantage we can take from someone else, because that is the game that our ancestors created. Everyone that matters is playing, so it must be right, eh?
