The thing is, humans can look at crosses without going into convulsions. That's evolution for you; one stupid linked mutation and the whole natural order falls apart, intelligence and self-awareness stuck in counterproductive lock-step for half a million years. I think I know what's happening back on Earth, and though some might call it genocide it isn't really. We did it to ourselves. You can't blame predators for being predators. We were the ones who brought them back, after all. Why wouldn't they reclaim their birthright?
Not genocide. Just the righting of an ancient wrong.
I've tried to take some comfort in that. It's—difficult. Sometimes it seems as though my whole life's been a struggle to reconnect, to regain whatever got lost when my parents killed their only child. Out in the Oort, I finally won that struggle. Thanks to a vampire and a boatload of freaks and an invading alien horde, I'm Human again. Maybe the last Human. By the time I get home, I could be the only sentient being in the universe.
