I simply can't stand the sight of people. Even hot women.
I'll also admit that the people of my own race, I can't stand them. It's not that I hate my own people, it's just that I hate everyone.
The way I would describe it is saturation. I simply can't take it anymore. I like nature and animals. Animals have the good sense not to take so many photos and videos of themselves all the time, or act all showy and important.
My philosophy is anti-humanism. It's not that I'm a monster. It's just that I think this story has gone as far as it can possibly go. We need to go away for a bit and let the animals take over again. And who knows, maybe one of their branches will evolve into "intelligent" life somewhere down the line.
