I don't predict that we are headed for peaceful coexistence. Unfortunately at least half of this country gets out of bed every day searching for something to be pissed off about and someone to blame it on and that isn't going to change until they have real concerns to occupy their time and energy. We have become the softest, most spoiled populace on the planet.
It's impossible for me to imagine people this unhappy, there is so much good to enjoy. Some people must enjoy being angry and screaming about it.
