If I didn't hate people so much, I'd be the same. Mostly I try to stay out of it and do what I love -- draw, listen to music, design things, play/mod video games, etc. There is not enough time in life to spend worried about the fact that everyone dies and everything will crumble, and that we are continuously hastening both processes. As you can see, occaisionally I get sucked back into the emotional and intellectual quagmire of learning about our most recent transgressions. I genuinely enjoy interacting with people most of the time, on an individual or small group basis, but people as a collective meta-level entity are just horrible. Not something I want to spend my time in or thinking about.
I encourage anyone who hasn't done so to disconnect themselves from all forms of mass news media for at least six months. See if your outlook on life and your disposition improves.
